M-5 made safeUrl() block data:image/svg+xml everywhere, including the
image-only sinks (<img src>, CSS url()) that Gallery's default images and
other SVG placeholders rely on. Loaded as an image, an SVG is rasterized
and never executes an inline <script>/onload= -- that only happens when
it's navigated to or loaded as an <iframe> document -- so M-5 over-blocked
the safe contexts and broke every published Gallery (and other components
using an SVG placeholder) using safeUrl's default images in prod.
Adds safeImageUrl(): identical javascript:/vbscript: handling to safeUrl,
but treats data: as an allowlist of image/* subtypes instead of a
blocklist -- allows all data:image/* (including svg+xml, with or without
base64), still blocks data:text/html and any other non-image data: type.
Swapped to safeImageUrl at IMAGE-src / CSS-image url() sinks only:
- Gallery.tsx img src + lightbox data-lb-src
- ImageBlock.tsx img src (toHtml)
- Logo.tsx / Navbar.tsx logo <img> src (their href/link targets keep safeUrl)
- style-helpers.ts sanitizeCssValue's url(...) handling (background-image
for HeroSimple/BackgroundSection/Section/CallToAction)
Left on safeUrl (href/iframe/form-action/navigation sinks, where
data:image/svg+xml must stay blocked): ButtonLink, Icon link, SocialLinks,
Menu/Navbar link hrefs, PricingTable buttonHref, _cta-helpers,
ContentSlider buttonHref, FeaturesGrid buttonUrl, FormContainer action
(via form-relay-wiring), MapEmbed/VideoBlock iframe src.

BlocksPanel dropped a new Image block with an explicit `src=""` prop, which
overrides ImageBlock's `src = PLACEHOLDER_SRC` default parameter (defaults
only apply when a prop is undefined, not when it's an empty string). Craft
then persisted `src:''`, and the canvas rendered a broken-image icon instead
of the placeholder.
- ImageBlock render now falls back to PLACEHOLDER_SRC whenever src is falsy
(belt-and-braces: also recovers any legacy saved src:'' state).
- BlocksPanel no longer passes src="" when dropping a new Image block, so
the craft default applies.
- ImageStylePanel now restores the placeholder (instead of blanking to '')
when the URL field is cleared.

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).

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.

- InputField/TextareaField/ContactForm: every control gets a
deterministic id (slugId() in utils/escape.ts, derived from the
field's name/label + index for ContactForm's looped fields -- no
Math.random) with a matching <label for=>; fields with no visible
label get an aria-label from the placeholder/name instead.
- StarRating: wrapped in role="img" aria-label="Rating: N out of M",
individual star glyphs marked aria-hidden.
- Navbar: the mobile hamburger toggle gets aria-label="Toggle
navigation menu", aria-controls="navbar-links", and aria-expanded
wired to flip true/false in the inline onclick handler.
- VideoBlock and MapEmbed: every exported <iframe> gets a title
(generic "Embedded video", or "Map of {address}" for MapEmbed).
- Decorative Font Awesome icons (ContentSlider arrows already covered
in the prior commit; SocialLinks, SearchBar, Testimonials stars) are
aria-hidden; SocialLinks' icon-only links get an aria-label naming
the platform alongside the existing title tooltip.

Extend detectVideoType to handle youtube.com/shorts/ID, youtube.com/live/ID,
youtube.com/watch?...&v=ID (v not the first query param), and Vimeo
private-hash URLs (vimeo.com/ID/HASH -> ?h=HASH player param). Existing
shapes (youtu.be/ID, youtube.com/embed/ID, youtube.com/watch?v=ID,
vimeo.com/ID, direct files) keep working. The emitted embed src still
passes through safeUrl unchanged.

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).

4px and 8px were imperceptible on typical image sizes. New scale
0/8/16/32/50% gives visible steps for None/S/M/L and keeps Full as
round.

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.
