/* ==========================================================================
   v2-flagship.css — Tabiji v2 FLAGSHIP layer (AGENT-FLAGSHIP) · 2026-06-09
   Enqueued site-wide after pages.css (handle: tabiji-v2-flagship, by MAIN).
   Scope strictly namespaced: .v2-home (front-page.php) and
   .v2-curriculum (page-curriculum.php).

   Hard rules honoured:
   - Brand palette tokens only. Gold TEXT on light surfaces uses
     var(--gold-text, #8A6320) — AA >= 4.5 on cream; fallback holds until
     MAIN lands the token in variables.css.
   - First viewport never starts at opacity:0. Hero entrances are
     transform-only (opacity stays 1). No-JS = fully settled state.
   - Animation: transform / opacity / SVG stroke only. Zero CLS.
   - All motion gated behind prefers-reduced-motion: no-preference.
   ========================================================================== */
