An adversarial pass found 5 Critical XSS sinks where props declared number/enum
in TypeScript were interpolated raw into exported HTML attribute values,
trusting the type — but nothing enforces it at runtime (AI update_props only
validates node_id; deserialized saved state is untyped JSON). Fixed all 5
(NumberCounter data-target, StarRating aria-label, FormContainer method,
ContactForm/InputField input type) plus 6 sibling sinks found by an exhaustive
audit of every attribute-value interpolation across src/components: a
JS-source injection into ContentSlider's inline setInterval script, a
prototype-pollution-adjacent allowlist gap in Section's divider-shape lookup,
TextareaField rows, Testimonials rating aria-label, HeroSimple textAlign, and
MapEmbed zoom. Adds shared sanitizeFormMethod/sanitizeInputType allowlist
helpers to utils/escape.ts alongside the existing escapeAttr/safeUrl/cssValue
primitives. Every fix is TDD'd: a malicious-value test reproduces the raw
injection against the pre-fix code, then passes after the fix.
502 tests green (npx vitest run), tsc + vite build green (npm run build).

Adds a single cssValue() sanitizer (src/utils/escape.ts) that strips
<>{};"'\ and neutralizes url(), safe for both style="..." attribute and
<style>...</style> element contexts. Applies it at every raw user-prop
CSS-value interpolation sink found via grep across src/components (colors,
sizes, gaps interpolated directly into style strings/<style> blocks),
including the highest-risk <style>-context sinks: ColumnLayout gap,
Menu/Navbar hover and background colors. Also Number()-coerces the
`columns` grid-template-columns sinks in Gallery/Testimonials/NumberCounter
as defense in depth. Regression tests assert </style><script> payloads are
neutralized and normal colors still render.

ContentSlider: autoplay's setInterval now pauses on mouseenter and on
document visibilitychange (tab hidden), resumes on mouseleave/visible,
and is always clearable (timer var + clearInterval). The aria-live
region is "off" while autoplay is silently auto-rotating and only
flips to "polite" on manual next/prev/dot navigation, so screen readers
aren't spammed with an announcement every `interval` ms (F-export
review Minor). Updates the one existing test that hard-coded
aria-live="polite" as always-on to match this intentional behavior
change.
(Countdown's ticking-interval-stops-at-zero nit shipped in the previous
commit alongside its node-id migration, since both touched the same
inline script.)
Adds regression tests locking in that MapEmbed/VideoBlock iframe src
attributes (built by string concatenation with literal `&` query
params) are HTML-entity-encoded via the existing escapeAttr(safeUrl())
pipeline -- verified already correct, no source change needed there.

ContentSlider, Tabs, and Gallery toHtml exports and their inline scripts
now carry ARIA semantics and keyboard support:
- ContentSlider: prev/next arrows and dot buttons get aria-labels, the
slide stack is wrapped in an aria-live="polite" region, and the
decorative chevron icons are aria-hidden.
- Tabs: tablist/tab/tabpanel roles, aria-selected/aria-controls/
aria-labelledby, and Left/Right/Home/End arrow-key navigation in the
inline script. The tab<->panel id scope is now derived from a
deterministic hash of anchorId/labels instead of Math.random, since
the ARIA linking ids must be stable across export runs.
- Gallery: the lightbox overlay gets role="dialog"/aria-modal/aria-label,
Escape closes it, and thumbnails are keyboard-operable (role="button"
tabindex="0" plus Enter/Space handling in the existing delegated
listener).

Each component defined a .craft.related.settings panel that was never
rendered -- the right panel renders only GuidedStyles (per-type
*StylePanel components), never .related.settings. Removed all dead
settings components across every component, their settings-only helpers
(including the dead uploadToWhp/showBrowser/handleBrowse asset-browse
blocks in Logo/Navbar/VideoBlock/FeaturesGrid, and CtasEditor in
_cta-helpers), and dropped the now-empty related keys. Render output,
.craft props/rules, and toHtml statics are unchanged.

Every user-controlled URL emitted by a component's static toHtml (href,
src, action, and CSS url()) now runs through escapeAttr(safeUrl(...))
before hitting the exported HTML string, closing the XSS gaps flagged
in the A2 review (PricingTable buttonHref was fully unescaped, Gallery/
HeroSimple/ImageBlock/VideoBlock/etc. lacked scheme filtering) plus a
few more found via a grep sweep of href=/src=/action=/url( inside
toHtml template strings: MapEmbed's iframe src and the shared
form-relay-wiring fallback form action (a javascript: form action
executes on submit).

Replace divergent, buggy local esc/escapeHtml helpers across 26 files with
imports from src/utils/escape (escapeHtml/escapeAttr). Attribute call sites use
escapeAttr, text-content sites use escapeHtml. Several toHtml outputs now
correctly escape & where old local escapers omitted it.

Real-world AI output frequently sends mismatched prop names (e.g.
items vs features, cta object vs buttonText/Href). The toHtml functions
of section/form/sections-folder components each defined a local
esc = (s: string) => s.replace(...) that crashed when called with
undefined, taking the auto-save export with it.
Patched every local esc() to coerce non-strings:
const esc = (s: any) => String(s ?? "").replace(...)
17 files touched; behavior unchanged for valid string inputs.
Also adds a WorkingIndicator (Claude Code-style spinner + rotating
phrase + elapsed seconds) shown in the modal footer while a generation
is in flight, replacing the disabled "Thinking..." placeholder.
Rebuilt the visual site builder from scratch using Craft.js, React 18,
and TypeScript. The new editor renders directly in the DOM (no iframe),
supports 40+ components, multi-page with shared header/footer, 16
templates, full-spectrum color/gradient controls, custom head code
injection, save/publish workflow, and auto-save.
