/* ============================================================
   §11 — MOTION, ONE NOTCH LOUDER (see DESIGN.md §11 for the full
   audit trail). Four signature moments + a supporting cast. Every
   motion here is transform / opacity / clip-path / SVG stroke only —
   never a layout property — so there is zero layout shift 320px→4k.
   Every motion has a reduced-motion + no-JS floor that renders it in
   its final resting state, so a headless reduced-motion render is
   pixel-equivalent to a no-JS render. Calm-and-expensive remains the
   resting state; when something moves, it moves slow, heavy, earned.

/* ----- Signature #1: the federation mark assembles itself on load.
   The lintel is already seated; the three pillars rise from below
   staggered (0/180/360ms), heavy ease-out 900ms. As each pillar seats,
   its 1px amber-bright weld hairline flares once along the top seam,
   then dims to nothing — the joint where three independent pillars
   lock into one shared lintel. Performed once; the mark is inert
   afterwards. Applied to BOTH the masthead mark and the hero ghost
   watermark (the ghost assembles slower, behind the hero copy).
   No-JS / reduced-motion → fully assembled at rest (see <noscript> and
