/* ---------- Logo mark "Pure Scope" (decorative; spec §4.3, motion rules §4.5) ----------
   At rest it is the ink trace (currentColor) plus the amber node; every other layer is invisible.
   Motion (WCAG 2.2.2): CSS only; plays once on load (0.25 s delay + 3.4 s = 3.65 s); replays on hover or
   keyboard focus of the brand link; never under reduced motion. Fill-mode is "backwards", so every layer drops
   back to its resting state when the run ends (holding the end frame with "forwards" on the filtered layers
   triggers a Chrome filter artifact).
   Timeline (% of 3.4 s): the beam sweeps x 1→31 over 0–44.118%; the lit trace's head tracks it (vertices at
   12.5% / 21.324%, node reached at 36.029%); the node lights over 30.882–36.029% and blooms; over 58–94% the
   spectrum drains left→right into the node, uncovering the settled ink trace. */
