+# sync.
+#
+# This is also the **PR build check**: it compiles Linux, macOS and Windows, so
+# a push that breaks any of them fails here. build-app.yml used to do that job
+# in parallel and publish nothing, which meant six OS builds per push and one
+# unreachable set of bundles; it is now releases-only.
+#
+# The cost of the swap, stated plainly: one prerelease per PR commit that
+# touches `app/**` — so the workflow prunes its own, keeping the newest
+# KEEP_PREVIEWS (see Lifecycle).
+#
+# ## Why not workflow artifacts
+#
+# Two attempts failed before this one, and both failure modes are worth knowing:
+#
+#  * `actions/upload-artifact@v4` cannot run here at all. It bundles
+#    `@actions/artifact` v2, whose `isGhes()` treats any GITHUB_SERVER_URL that
+#    is not github.com / *.ghe.com / *.localhost as GitHub Enterprise Server and
+#    throws before making a single request. act_runner sets that variable to this
+#    Gitea instance, so every platform died with "GHESNotSupportedError" — after
+#    the whole Tauri build had been paid for (run #265).
+#  * `@v3` uploads *succeed*, and the files are downloadable by direct URL — but
+#    Gitea does not **list** them: `/api/v1/…/runs/<id>/artifacts` reports
+#    `total_count: 0` and the run page shows nothing (verified on run #267).
+#    A build nobody can find is not a build.
+#
+# So previews publish the same way every other workflow here does: curl to the
+# Gitea releases API. One release per preview, tagged `preview-<sha>`.
+#
+# ## Lifecycle
+#
+# The `preview-` tag prefix is deliberate. `cleanup-releases.yml` keeps the most
+# recent `v<major>.<minor>.<patch>` releases and separately deletes every release
+# whose tag does *not* start with `v[0-9]` — so previews never crowd the real
+# release list, and a manual cleanup sweeps any this workflow missed.
+#
+# But that cleanup is a manual, dry-run-by-default action, and one prerelease per
+# pushed commit accumulates faster than anyone runs it. So the last job here
+# prunes previous previews itself, keeping the newest few. Bundles are ~130 MB a
+# release; the point of a preview is the build you are testing now.
+#
+# `sync-release.yml` is workflow_dispatch-only, so nothing here reaches GitHub.

+    not give it one; the app CSP does not apply, because it is a top-level document rather than a
+    frame, and the token gate is what protects the port in both cases; and the window is owned by
+    the *session*, so the supervisor's teardown closes it rather than leaving a window onto a
+    viewer that no longer exists. It closes with `destroy()`, never `close()`, to stay clear of
+    `CloseRequested`. The pane drops its iframe while popped out — two viewers can both *drive*
+    the browser.
+  - **`page.rs` opens a page, which is the one thing the pane could not do.** A URL plus a
+    viewport: launch a browser in the container, `browser.bind()` it so the pane shows it, and
+    keep the handle. Serves auth (the OAuth callback listener is *in* the container, so a
+    container-side browser closes the loop with no host round trip and no auth bridge) and dev
+    servers on container loopback. **Verified: a second client cannot join a bound browser** —
+    `chromium.connect()` against the published endpoint times out in every URL form, because that
+    socket speaks the dashboard's transport, not the public connect protocol. So whoever launches
+    is the only process that can drive, which is why the helper is resident and why live resize
+    applies to pages *we* opened and never to `@playwright/mcp`'s (those take `--viewport-size` /
+    `PLAYWRIGHT_MCP_VIEWPORT_SIZE` at launch). Control is a polled JSON file in `/tmp` — no port,
+    no second listener — and a re-open with a helper already up *navigates* rather than
+    relaunching, so a session signed in on one page survives to the next.
+  - **Resizing the window does not resize the page.** The viewer is a CDP screencast: a bigger
+    window is the same pixels drawn larger. `page.setViewportSize()` is what reflows (measured
+    against a `@media (max-width: 900px)` rule), and match-window mode pushes the pop-out's
+    settled `Resized` size into it — debounced by generation counter, since a drag emits
+    continuously and each one costs a container exec.
+  - **`lib.rs`'s `on_window_event` fires for every window and must stay guarded on

+A global `AppSettings::ca_cert_path` with a per-project `Project::ca_cert_path` override, accepting
+a single certificate file **or** a directory. Follows the SSH/AWS host-mount pattern: read-only
+bind mount at `/tmp/.host-ca`, applied by the entrypoint on every start, so it survives recreation,
+migration and Reset. Four things here are not obvious:
+
+- **`update-ca-certificates` globs `*.crt`, case-sensitively.** A `.pem` that is merely copied into
+  `/usr/local/share/ca-certificates/` is ignored in total silence. Certificates are *renamed* —
+  `container_cert_name()` in Rust, mirrored in a few lines of shell in `entrypoint.sh` (the Rust
+  side carries the unit tests). A single-file mount lands at `/tmp/.host-ca/<name>.crt` so the
+  entrypoint only ever sees a directory and the file keeps a recognisable name.
+- **The system store is not enough.** Only curl/git/apt read it. Node — and therefore Claude Code
+  itself — needs `NODE_EXTRA_CA_CERTS`; Python/requests need `REQUESTS_CA_BUNDLE`/`SSL_CERT_FILE`;
+  Chrome/Chromium read neither and want their own NSS database at `~/.pki/nssdb`, seeded with
+  `certutil` (`libnss3-tools`, added to the image for this). The NSS step warns and continues if
+  `certutil` is missing rather than failing the start.
+- **Those env vars are set from Rust at creation, never exported by the entrypoint.** A terminal
+  session is a `docker exec`, which inherits the container's configured env and sees nothing the
+  entrypoint exported — the same lesson that made `$BROWSER` an image-level `ENV`. The bundle path
+  is deterministic (`/etc/ssl/certs/ca-certificates.crt`), so Rust can set them up front. They are
+  emitted **empty** when no CA is configured, for the `MANAGED_AUTH_KEYS` reason: `docker commit`
+  bakes env into the snapshot image. Empty is safe — verified on Ubuntu 24.04 that curl, `openssl
+  s_client` and Python's `ssl` behave exactly as with the vars unset.
+- **`triple-c.ca-fingerprint` covers the certificate *bytes*, not just the path.** Replacing a
+  rotated CA at the same location must recreate the container; the copy inside is made once, at
+  start, so nothing else would notice. The entrypoint is stamped/idempotent on restart, and
+  actively **removes** `triple-c-*.crt` when the setting is cleared — `/usr/local/share` rides the
+  project's snapshot image, so turning the feature off has to undo, not merely stop.

 ### Container Lifecycle
 
 Containers use a **stop/start** model (not create/destroy). Installed packages persist across stops. The `.claude` config dir uses a named Docker volume (`triple-c-claude-config-{projectId}`), nested inside the home volume (`triple-c-home-{projectId}`), so OAuth tokens and Claude Code config survive container stop/start *and* container recreation.

+### The Browser Tab
+
+When Claude drives a browser with Playwright inside the container, the **Browser** tab shows you
+that browser live — and lets you take it over with your own mouse and keyboard.
+
+It is **off by default and opted into per project**, and it never installs anything on its own.
+Opening the tab only *probes* the container, so it can tell you what is missing before you ask for
+a view; installing Playwright and downloading a browser are separate, labelled buttons that state
+what they cost before you press them. See
+[What's Inside the Container](#whats-inside-the-container) for why the browser itself is not
+pre-installed.
+
+Press **Start browser view** and the pane fills with Playwright's own dashboard, running inside the
+container and reached over a token-gated listener on your machine's loopback address. Nothing is
+exposed off the machine.
+
+#### Opening a page yourself
+
+**Open a page…** launches a browser inside the container at a URL and viewport you choose, and
+publishes it to this pane. Two uses:
+
+- **A sign-in page.** The callback the tool is waiting for is a listener *inside* the container, so
+  a container-side browser completes the login without anything crossing to your host browser.
+  When a long URL appears in a terminal, the prompt that offers to open it on your host now also
+  offers **In container**, which does the same thing in one click.
+- **A dev server.** `http://localhost:5173` inside the container is reachable with no port mapping
+  and nothing exposed to your network — which is how you watch a UI Claude is building, and click
+  around it yourself.
+
+The **viewport** is the page's own resolution, and it is not the same thing as the window size.
+The pane shows a video of the browser, so a bigger window draws the same pixels larger; changing
+the viewport is what makes the layout actually reflow. Pick a preset or type a size.
+
+Note the limit, because it is not obvious: a browser Claude opened through `@playwright/mcp` can
+be *watched* but not resized — a published browser admits only the client that launched it. Set
+its size with `PLAYWRIGHT_MCP_VIEWPORT_SIZE=1920x1080` in the project's environment variables
+instead.
+
+#### Watching it while you work
+
+Press **Open in own window** and the view moves out of the tab into a window of its own — put it on
+a second monitor, or turn on **Keep on top** and let it float above the app while you work in a
+terminal. **Match window** goes further: the page's viewport follows the window as you drag it, so
+the pop-out becomes a responsive-design ruler. It applies to pages opened with **Open a page…**,
+for the reason above. This is a window change only: the browser and the view keep running throughout, so
+popping out and back costs nothing and interrupts nothing.
+
+While the view is in its own window the tab shows a placeholder rather than a second copy of it —
+two viewers would both be able to *drive* the browser, and two cursors on one page is not useful.
+**Put back in tab**, or just closing the window, brings it back.
+
+The window belongs to the view, not to the tab: closing the project's home tab leaves it open, and
+stopping the view — by pressing **Stop**, stopping the container, or removing the project — closes
+it, because a window showing a viewer that no longer exists is worse than no window.

+lost the first time any of those happens.
+
+The status line under the field tells you how many certificates were found and the names they will
+be installed as inside the container. That rename matters: the container's trust store only reads
+files ending in `.crt`, so a `.pem` is renamed rather than merely copied, which is the step that is
+easiest to get wrong by hand.
+
+Inside the container the certificate is trusted by:
+
+| Consumer | How |
+|---|---|
+| curl, git, apt, wget | the system trust store (`update-ca-certificates`) |
+| Node, npm, **Claude Code itself** | `NODE_EXTRA_CA_CERTS` |

+
+A per-project override lives in **Project Home → Config → Access**; leave it blank to use this

+Each recreation moves the `triple-c-snapshot-{projectId}:latest` tag, leaving the image it pointed
+at before untagged but still on disk — multiple gigabytes per recreation. `sweep_orphaned_snapshots`
+clears those after a recreation and after a migration is accepted. It only ever removes images that
+are **both** untagged *and* labelled `triple-c.managed=true`, so a live snapshot tag and a
+migration's `pre-migration-*` rollback pin are structurally out of reach, and removal is unforced so
+Docker itself refuses while any container — including a stopped project's — is still built from the
+image.
+7. **Reset**: Container, snapshot image **and both named volumes** all removed, then recreated from the clean base image. `remove_project_volumes` deletes `triple-c-home-{projectId}` and `triple-c-claude-config-{projectId}`, so `~/.claude`, `~/.claude.json`, the OAuth login, installed skills, session transcripts and the scheduler's tasks are all lost.
+
+### Base-Image Migration
+
+A container is created from `triple-c-snapshot-{projectId}:latest` whenever that image exists, and
+every recreation re-commits it. So without an explicit act, a project stays on the base image it was
+first built from **forever** — it never picks up a new `/usr/local/bin` shim, a new `socat`, or a
+security update. **Update container base…** (Project Home → overflow menu) is the non-destructive
+way out; Reset is the destructive one. `docker/migration.rs` owns it.
+
+- **Staleness is surfaced, not acted on.** `triple-c.base-image-id` records the lineage and
+  `get_container_staleness` reports it as a banner, but it is deliberately *not* compared in
+  `container_needs_recreation`. Comparing it there would recreate every project *from its own
+  snapshot* on the next base bump: churn on the old base, and the "you should migrate" signal
+  consumed without migrating. A missing lineage label means "unknown, probe instead" — never
+  "stale".
+- **What comes across**: the apt package delta and user-authored files, computed by diffing two
+  filesystem manifests through dpkg ownership and presence-in-the-new-base. (`docker diff` is
+  useless here — on a snapshot-derived container it only reports changes since the last commit.
+  Measured on a real project, manifest diffing turned 8,677 raw path differences into 2 genuinely
+  user-authored ones.) Both named volumes are untouched at every step, so `$HOME`, the OAuth login,
+  skills, transcripts and scheduler tasks simply re-attach.
+- **What does not**: `/etc` is reported but never copied — the old lineage has
+  `/etc/apt/sources.list.d/nodesource.sources` where the current base has `nodesource.list`, and
+  having both breaks every `apt-get update`. `/var` is not copied either, and that is the one way
+  migration is *more* destructive than an ordinary recreate: a database under `/var/lib` rides along
+  on a recreate, but a migration builds from the base and the apt replay hands back an empty
+  cluster. `unpreserved_data()` names those directories in the pre-flight, the banner and the final
+  report.
+- **Crash-safety**: `:latest` keeps pointing at the old lineage until the final commit, so any
+  failure before that self-heals — the next start just recreates from the old snapshot. After the
+  container swap, a `triple-c.migration-state=in-progress` label plus a persisted state file let the
+  app offer **resume** or **rollback**. Rollback restores the system layer only; work done in
+  `$HOME` during a migrated session survives it.
+
+### Mounts
+
+| Target in Container | Source | Type | Notes |
+|---|---|---|---|
+| `/workspace/<mount-name>` | Each configured project folder | Bind | Read-write; one per folder |
+| `/home/claude` | `triple-c-home-{projectId}` | Named Volume | Home directory; survives stop/start and recreation |
+| `/home/claude/.claude` | `triple-c-claude-config-{projectId}` | Named Volume | Nested inside the home volume; Docker gives the more specific mount precedence |
+| `/tmp/.host-ssh` | SSH key directory | Bind | Read-only; entrypoint copies to `~/.ssh` |
+| `/tmp/.host-aws` | AWS config directory | Bind | Read-only; entrypoint copies to `~/.aws`; for Bedrock auth |
+| `/tmp/.host-ca` | CA certificate file or directory | Bind | Read-only; entrypoint installs into the system and NSS stores |
+| `/var/run/docker.sock` | Host Docker socket | Bind | If "Allow container spawning" is ON |
+
+These two named volumes are the only ones a project owns. Both are removed by Reset and by project
+removal, and by nothing else.
+
+### Corporate CA Certificates
+
+A global **Certificates** setting (`AppSettings::ca_cert_path`) with a per-project override
+(`Project::ca_cert_path`), accepting a single certificate file **or** a directory. It follows the
+SSH/AWS host-mount pattern — read-only bind mount at `/tmp/.host-ca`, applied by the entrypoint on
+every start — so it survives recreation, migration and Reset.
+
+- **Certificates are renamed to `.crt`.** `update-ca-certificates` globs `*.crt`, case-sensitively;
+  a `.pem` merely copied into `/usr/local/share/ca-certificates/` is ignored in total silence.
+  `container_cert_name()` in Rust does the renaming, mirrored in a few lines of shell in the
+  entrypoint. A single-file mount lands at `/tmp/.host-ca/<name>.crt`, so the entrypoint only ever
+  sees a directory.
+- **The system store is not enough.** Only curl, git and apt read it. Node — and therefore Claude
+  Code itself — needs `NODE_EXTRA_CA_CERTS`; Python and requests need
+  `REQUESTS_CA_BUNDLE`/`SSL_CERT_FILE`; Chromium reads neither and wants its own NSS database at
+  `~/.pki/nssdb`, seeded with `certutil` (from `libnss3-tools`). The NSS step warns and continues
+  rather than failing the start.
+- **Those env vars are set from Rust at creation, never exported by the entrypoint.** A terminal
+  session is a `docker exec`, which inherits the container's configured env and sees nothing the
+  entrypoint exported — the same lesson that made `$BROWSER` an image-level `ENV`. They are emitted
+  **empty** when no CA is configured, because `docker commit` bakes env into the snapshot image.
+- **`triple-c.ca-fingerprint` covers the certificate bytes, not the path.** Replacing a rotated CA
+  at the same location still forces the recreation that copies it in. Clearing the setting actively
+  **removes** `triple-c-*.crt` from the container — `/usr/local/share` rides the project's snapshot,
+  so turning the feature off has to undo, not merely stop.
+
+### Container Spawning (Sibling Containers)
+
+When "Allow container spawning" is enabled per-project, the host Docker socket is bind-mounted into the container. This allows Claude Code to create **sibling containers** (not nested Docker-in-Docker) that are visible to the host. The entrypoint detects the socket's GID and adds the `claude` user to the matching group.
+
+If the Docker access setting is toggled after a container already exists, the container is automatically recreated on next start to apply the mount change. The named config volume (keyed by project ID) is preserved across recreation.
+
+### Docker Socket Path
+
+The socket path is OS-aware:
+- **Linux/macOS**: `/var/run/docker.sock`
+- **Windows**: `//./pipe/docker_engine`
+
+Users can override this in Settings via the global `docker_socket_path` option.
+
+## Models and Authentication
+
+### Authentication Modes
+
+Each project can independently use one of:
+
+- **Anthropic** (OAuth or shared token): either the shared `claude setup-token` token injected as `CLAUDE_CODE_OAUTH_TOKEN` (see below), or a per-container `claude login`. An interactive login's token lives in the config volume and survives container stop/start and recreation — but **not** a Reset, which deletes the volumes.
+- **AWS Bedrock**: Per-project AWS credentials (static keys, profile, or bearer token). SSO sessions are validated before launching Claude for Profile auth.
+- **Ollama**: Connect to a local or remote Ollama server via `ANTHROPIC_BASE_URL` (e.g., `http://host.docker.internal:11434`). Requires a model ID, and the model must be pulled (or used via Ollama cloud) before starting the container.
+- **llama.cpp**: Connect to a local or remote `llama-server` via `ANTHROPIC_BASE_URL` (e.g., `http://host.docker.internal:8080` — 8080 is `llama-server`'s default port). `ANTHROPIC_AUTH_TOKEN` is set to a placeholder; `llama-server` ignores it unless it was started with `--api-key`.
+- **OpenAI Compatible**: Connect through a gateway that implements the **Anthropic Messages API**, via `ANTHROPIC_BASE_URL` + `ANTHROPIC_AUTH_TOKEN`. API key stored securely in OS keychain. Triple-C can run that gateway for you — see [Model Gateway](#model-gateway-litellm-sibling-container).
+
+> **The endpoint must speak the Anthropic Messages API.** Claude Code only ever sends
+> `POST /v1/messages?beta=true` in Anthropic Messages format to `ANTHROPIC_BASE_URL` — it never
+> speaks OpenAI's `/v1/chat/completions`. So a server that exposes *only* an OpenAI-compatible API
+> (plain vLLM, text-generation-inference, LocalAI, OpenRouter, …) will **not** work behind any of
+> these backends. What does work: **LiteLLM**, which exposes an Anthropic-shaped route, and
+> **Ollama** and **llama.cpp**, both of which implement `POST /v1/messages` natively — which is why
+> they get first-class backends of their own rather than going through a translation layer.
+
+#### Model alias variables
+
+The `opus` / `sonnet` / `haiku` / `fable` aliases in Claude Code resolve to Anthropic model IDs by
+default. Against a local server those IDs do not exist, so anything that uses an alias fails —
+most visibly the **background** calls (conversation titles, summaries), which use `haiku`.
+
+For every backend that points at a custom endpoint (Ollama, llama.cpp, OpenAI Compatible),
+Triple-C therefore sets all four:
+
+| Variable | Value |
+|---|---|
+| `ANTHROPIC_DEFAULT_OPUS_MODEL` | the backend's configured model ID |
+| `ANTHROPIC_DEFAULT_SONNET_MODEL` | the backend's configured model ID |
+| `ANTHROPIC_DEFAULT_HAIKU_MODEL` | the **Background model** override, else the configured model ID |
+| `ANTHROPIC_DEFAULT_FABLE_MODEL` | the backend's configured model ID |
+
+A local server usually serves exactly one model, so pointing every alias at it is the right
+default. If you run a second, smaller model for cheap background work, set **Background model**
+(Config → Model, and in global Backend settings) and only the Haiku alias moves.
+
+These are *not* set for the Anthropic or Bedrock backends, which reach servers that really do host
+the Anthropic model IDs. Triple-C manages all four names, so they cannot be set as custom
+environment variables. (`ANTHROPIC_SMALL_FAST_MODEL` is deprecated and is not used.)
+
+> **Note:** Ollama, llama.cpp and OpenAI Compatible support is best-effort. Claude Code is designed for Anthropic models, so some features (tool use, extended thinking, prompt caching, etc.) may not work as expected with non-Anthropic models behind these backends.
+
+### Model Gateway (LiteLLM sibling container)
+
+For providers that only speak OpenAI's API, Triple-C can run **LiteLLM** as a sibling container
+(`docker/gateway.rs`, `gateway-container/`) that gives Claude Code the Anthropic-format front end it
+requires. Settings → Gateway configures the provider prefix (`openai`, `azure`, `gemini`, `groq`,
+…), an optional API base override, the models to serve, and the host port (default `4000`). A
+project then consumes it with the OpenAI Compatible backend. It mirrors the STT container's
+lifecycle, including auto-start with the app.
+
+Its bind address is **detected, never `0.0.0.0`**. Unlike STT, the consumers are *project
+containers*, so loopback alone is not always enough: Docker Desktop binds `127.0.0.1` and advertises
+`host.docker.internal`; native Linux binds the default bridge gateway (`172.17.0.1`) and advertises
+the same literal. `GatewayBinding` derives the bind address and the advertised `base_url` together
+so the two cannot drift. A wildcard bind would be LAN-reachable — Docker's rules precede host
+firewalls — in front of a config file holding a billed provider key. A LiteLLM `master_key` is
+**always** set, because LiteLLM without one accepts any key.
+
+### Shared Claude Authentication Token
+
+Rather than running `claude login` in every container, `claude setup-token` can be run once
+(`commands/auth_token_commands.rs`). The flow borrows a running container, runs the CLI on a PTY,
+and the long-lived token it prints is stored in the OS keychain — it is never returned to the
+frontend and never logged. Streamed output passes through a chunk-boundary-safe redactor that masks
+anything resembling an `sk-ant-` secret.
+
+The token is injected as `CLAUDE_CODE_OAUTH_TOKEN` into every project where the backend is
+Anthropic, the project has not opted out (`use_shared_auth_token`, default `true`), and a token is
+actually stored. It is a reserved env key, so it cannot be hand-set as a custom variable.
+
+Rotation is tracked with a random id (not a hash of the token) mirrored into the
+`triple-c.claude-token-version` label — a hash in a `docker inspect`-readable label would be an
+offline verification oracle. Acquiring, rotating, revoking or opting out changes that label, which
+forces a container recreation on the next start; that is when a container picks the token up or has
+it cleared.

+(`/workspace/*/.claude`, `/workspace/*/.mcp.json`). Overview renders these as tiles.
-5. **Restart**: Existing container restarted; if any `triple-c.*` label no longer matches the project's settings, the container is committed to a snapshot image, removed, and recreated from that snapshot — so installed packages survive
-6. **Reset**: Container, snapshot image **and both named volumes** all removed, then recreated from the clean base image. `remove_project_volumes` deletes `triple-c-home-{projectId}` and `triple-c-claude-config-{projectId}`, so `~/.claude`, `~/.claude.json`, the OAuth login, installed skills, session transcripts and the scheduler's tasks are all lost.

+//! Open a page in the container's browser, and resize it while it runs.
+//!
+//! The pane [watches](super) browsers something else published. This opens one:
+//! the user hands it a URL, it launches a browser inside the container,
+//! publishes it with `browser.bind()` so the pane picks it up, and holds the
+//! handle so the page can be navigated and **resized** afterwards.
+//!
+//! ## Why the handle has to be held
+//!
+//! Verified against a real bound browser: a second client cannot join one.
+//! `chromium.connect()` against the published endpoint times out in every URL
+//! form — the descriptor's socket speaks the dashboard's own transport, not the
+//! public connect protocol. So whoever launches the browser is the only process
+//! that can ever drive it. That is the whole reason this helper is a resident
+//! process rather than a one-shot `node -e` that exits.
+//!
+//! It also draws the line for the feature: pages *this* opens can be resized
+//! live; a browser `@playwright/mcp` launched can only be watched, and its size
+//! is whatever `--viewport-size` it was given.
+//!
+//! ## Control channel
+//!
+//! A JSON file in `/tmp`, polled by the helper. No port, no second listener, no
+//! addition to the proxy's attack surface — and it composes with the one exec
+//! path this codebase already has. Writes go through `node -e` rather than
+//! shell redirection so a URL never touches a shell.
+//!
+//! ## Viewport, and why it is the interesting part
+//!
+//! `page.setViewportSize()` genuinely reflows: measured on a page carrying a
+//! `@media (max-width: 900px)` rule, the rule fires at 800×600 and clears at
+//! 1440×900. Resizing the *window* the pane lives in does nothing of the sort —
+//! the viewer is a CDP screencast, so a bigger window is the same pixels drawn
+//! larger. This is what makes the pop-out usable as a responsive-design ruler.

+//! The window loads the *same* token-bearing loopback URL the pane's iframe

+//! - It is a **remote-origin** webview. No capability lists this window, so it
+//!   has no IPC surface at all — `invoke` is not reachable from it, which is
+//!   exactly right for a page served out of a container. Do not add one.
+//! - The app CSP does not apply, and does not need to: `frame-src` exists to
+//!   constrain what the *app's* document may embed, and this is not embedded.

+//!
+//! ## Lifetime
+//!
+//! The window is owned by the session, not by the user's patience: when a view
+//! stops — the user pressed Stop, the container went away, the viewer died —
+//! the supervisor's teardown calls [`close`], because a window left showing a
+//! dead viewer is worse than no window. The reverse is not true; closing the
+//! window leaves the view running, and the pane takes it back into the tab.

+//! Corporate CA certificate injection.
+//!
+//! Users behind a TLS-terminating corporate proxy need their organisation's
+//! root CA inside every container, or **every** HTTPS call fails — npm, pip,
+//! git, curl, the Playwright browser, and Claude Code's own API calls.
+//!
+//! The mechanism follows the SSH/AWS host-mount pattern in [`super::container`]:
+//! a host path is bind-mounted **read-only** into the container and
+//! `entrypoint.sh` applies it on every start. That is what makes it durable
+//! across container recreation, base-image migration and Reset — a certificate
+//! installed by hand inside a running container is lost the first time any of
+//! those happen.
+//!
+//! ## Two things that are easy to get wrong
+//!
+//! 1. **`update-ca-certificates` only reads `*.crt`.** It globs
+//!    `/usr/local/share/ca-certificates/*.crt` case-sensitively, so a `.pem`
+//!    (the far more common export format) that is merely *copied* in is
+//!    silently ignored — no warning, no error, just a container that still
+//!    cannot speak HTTPS. Certificates must be **renamed**, which is what
+//!    [`container_cert_name`] does.
+//!
+//! 2. **The system trust store is not enough.** Only curl/git/apt read it.
+//!    Node — and therefore Claude Code itself — needs `NODE_EXTRA_CA_CERTS`,
+//!    Python/requests need `REQUESTS_CA_BUNDLE`/`SSL_CERT_FILE`, and
+//!    Chrome/Chromium read neither: they have their own NSS database at
+//!    `~/.pki/nssdb`, seeded by `certutil` in the entrypoint.
+//!
+//! ## Why the env vars are set from Rust and not exported by the entrypoint
+//!
+//! An `export` in `entrypoint.sh` reaches only the entrypoint's own children.
+//! Every terminal session is a separate `docker exec`, which inherits the
+//! *container's* configured env and sees nothing the entrypoint exported —
+//! the same lesson that forced `$BROWSER` to become an image-level `ENV` for
+//! the URL relay shim. Since the bundle path written by
+//! `update-ca-certificates` is deterministic ([`CA_BUNDLE_PATH`]), Rust can set
+//! all three vars at container creation, where `docker exec` will see them.

+
+The mark is a container with its right wall opened, so the enclosure itself is the letter **C**,
+holding a `>_` prompt. Container plus shell, in one closed shape — no type inside the icon, so
+nothing goes illegible when the app is 16 px tall in a taskbar.
+
+## Files
+
+| File | What it is |
+|---|---|
+| `triple-c-mark.svg` | The mark alone, transparent. Use on any ground. |
+| `triple-c-mark-small.svg` | Optical variant for 32 px and below. |
+| `triple-c-icon.svg` | The app icon: mark at 70% on a `#0D1117` tile, 22% corner radius. |
+| `triple-c-icon-small.svg` | The app icon at small sizes — small mark, drawn at 82%. |
+| `triple-c-lockup-dark.svg` | Horizontal lockup for dark backgrounds. Wordmark is outlined, so no font is needed to render it. |
+| `triple-c-lockup-light.svg` | The same for light backgrounds. |
+| `triple-c-icon-1024.png` | Master raster, generated. |
+| `build-icons.py` | Regenerates every packaged icon from the SVGs. |
+
+## Palette
+
+| Role | Dark ground | Light ground |
+|---|---|---|
+| Frame | `#58A6FF` (`--accent`) | `#1F6FEB` (`--accent-emphasis`) |
+| Prompt | `#F0821E` | `#C4610F` |
+| Tile | `#0D1117` (`--bg-primary`) | — |
+| Wordmark | `#E6EDF3` (`--text-primary`) | `#131C25` |
+
+The frame and prompt colours are the app's own accent tokens from `app/src/index.css`, which is why
+the icon sits on the app's chrome instead of fighting it. Orange is the only equity carried over
+from the previous marks, and it is now an accent rather than a background.
+
+## Two sources, not one
+
+`build-icons.py` renders sizes ≥ 48 px from `triple-c-icon.svg` and sizes ≤ 32 px from
+`triple-c-icon-small.svg`. At small sizes the cursor bar closes up against the chevron and a 12 px
+frame stroke resamples to a grey smear, so the small variant drops the cursor, widens the mouth,
+thickens the strokes and draws the mark larger inside the tile.
+
+This matters most for `icon.ico`: Windows picks the 16 px entry for the window corner and 24/32 px
+for the taskbar. The previous `.ico` contained a *single* 16 px image, which Windows then upscaled
+everywhere else — the likely cause of `screenshot_for_fix/task_bar_icon_not_correct.png`. The
+current one carries 16, 24, 32, 48, 64, 128 and 256, each rendered from vector rather than
+downsampled from one bitmap.
+
+## Regenerating
+
+```bash
+pip install cairosvg pillow
+python3 branding/build-icons.py
+```
+
+Writes `app/src-tauri/icons/{32x32,128x128,128x128@2x,icon}.png`, `icon.ico`, `icon.icns`,
+`app/public/favicon.svg` and `branding/triple-c-icon-1024.png`. Do not hand-edit those — edit the
+SVG and re-run.
+
+The lockups are committed sources, not generated: their wordmark is Liberation Mono Bold converted
+to outlines (`-1.6` tracking, 44 px cap height), so re-cutting it needs the font and `fonttools`.

+The marks Triple-C shipped before the current one, kept for reference.
+
+| File | Notes |
+|---|---|
+| `triple-c-app-logo.png` | First mark: orange tile, overlapping C letterforms, "TRIPLE-C / CONTAINERIZED CODING" set inside the icon. |
+| `triple-c-app-logov2.png` | Second mark: orange sunburst with "Triple-C / Coding Container" over it, transparent ground. |
+
+Both were drawn at poster size and carried type inside the icon, so nothing in them survived the
+16–32 px range where an app icon actually lives. Neither is referenced by the app or the build.
