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.

- 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.

The editor rendered layout="single" as an interactive carousel (prev/next
buttons, dot indicators, currentIndex state) but toHtml exported a static
stacked list of ALL testimonials -- a structural mismatch. This codebase's
static export has no published-JS interactivity for this component, so
static-parity is the lower-risk fix: the editor's single view now renders
just the first testimonial (no carousel chrome), and toHtml exports
exactly that one card. Grid layout is 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.

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.

Three related features:
1. Dynamic CTA buttons on HeroSimple, CTASection, CallToAction.
New shared ctas[] array (text + href + variant + target) replaces the
primary/secondary pair. Settings panel gets add/remove/reorder controls.
Legacy fields stay readable for backwards compat — first user edit
migrates the section onto the new array.
2. Anchor IDs on all layout/section components (Container, Section,
BackgroundSection, ColumnLayout, plus 6 section blocks done by parallel
subagent, plus Hero/CTA/CallToAction). Anchor input lives in the
settings panel with an "auto from heading" button that walks the
subtree for the first Heading.text. Renders as id="..." on the
outermost element so #anchor URLs resolve.
3. Edit-with-Sitesmith targeted invocation. Right-click → "Ask Sitesmith"
and a button at the top of the right-side settings panel both open the
modal pre-targeted at the selected node. The node's serialized subtree
is sent to the server; system prompt is augmented to require a patch
with replace_node. Editor lifts modal state into a new SitesmithContext.

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.
