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).

Two components of the det-id bug class were missed in the earlier migration:
NumberCounter's wrapper/counter ids and count-up script, and the shared
form-relay-wiring fid (used by ContactForm/FormContainer). Both used
Math.random() for exported HTML ids, breaking caching/diffing across exports.
Migrate both to scopeId(nodeId, fallbackSeed, prefix), threading nodeId
through NumberCounter.toHtml and relayFormWiring (via ContactForm.toHtml and
FormContainer.toHtml, both now passing nodeId as their 3rd arg).
- 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.

successMessage was collected in props (and FormStylePanel already had a
live "Success Message" input for it) but toHtml never emitted it anywhere.
The form-sender relay delivers success via a full-page 303 redirect to
thankYouUrl or a hosted thanks.php page -- there is no in-page JS today
that could reveal an inline success element. Emit it as
data-whp-success-message (escaped) on the <form>: forward-compatible for a
future AJAX submission mode, without implying a live mechanism that
doesn't exist yet.

Fix non-relay form output to match pre-change byte-for-byte by conditionally omitting the honeypot and fields lines when empty. Add backward-compat regex assertion to catch extra blank lines.
