/* ============================================================================
 * straza.ai - marketing landing page  ·  "Watchtower" (marketing surface)
 * ----------------------------------------------------------------------------
 * Token vocabulary is lifted verbatim from docs/site/assets/site.css so the
 * marketing page and the docs site stay one system. LAYOUT diverges (this is a
 * single full-bleed marketing page, not the docs shell) but TOKEN DISCIPLINE
 * does not: never hardcode a colour/size/radius - always a token.
 *
 *   --accent (beacon amber) = brand + focus + interactive (sanctioned on this
 *                             low-density brand surface, BRAND.md §0.3/§1.2)
 *   --ok/--warn/--danger/--unknown = trust semantics ONLY, never decoration
 *   --beacon-ground = the fixed dark ground brand artwork renders on, both
 *                     themes (BRAND.md §1.1 identity fill / §4.1 colour modes:
 *                     bright amber reads on dark only - 1.80:1 on white FAILS,
 *                     so the amber animated lockup sits on this constant ground)
 *
 * No webfonts, no external assets, no fetch: system UI + system mono, inline /
 * relative SVG only. Works from file://.
