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).

renderNode now passes the Craft node id as toHtml's 3rd argument
(props, childrenHtml, nodeId). Backward compatible: the resolver map is
untyped (any), so existing 2-arg toHtml implementations/tests are
unaffected. Adds scopeId()/stableHash() helpers in utils/escape.ts:
scopeId derives a scope string from the node id (deterministic AND
unique, since Craft node ids are unique per node and stable across
repeated exports of the same page) with a stableHash(seed) fallback for
legacy call sites without a node id.

Adds craft/src/utils/escape.ts as the single exported escaping/URL-safety
util (escapeHtml, escapeAttr, safeUrl) for later hardening tasks to
consolidate the 27 divergent local copies into. html-export.ts now
imports escapeHtml from it instead of keeping a private copy.
