/* Heritage Hub — public (marketing/legal) pages.
 *
 * Colours are GENERATED from the app's one palette source
 * (app/lib/core/theme/brand_colors.dart) by scripts/gen_brand_css.py — see
 * the marked block below. Never hand-edit those values; change BrandColors
 * and re-run the script, so the app and the public pages cannot drift.
 *
 * The public pages are DELIBERATELY always cream — no dark-mode override.
 * (Candid review 2026-10-23: "pick one theme for all public pages"; the
 * signed-in app alone follows the device.) Fonts: Newsreader (headings) +
 * Figtree (text), loaded by each page from Google Fonts (CSP already allows
 * fonts.googleapis.com / fonts.gstatic.com).
