/* ============================================================
   v100 — Base styles & shared glass components (blueprint §7–§9)
   ------------------------------------------------------------
   - Every color comes from tokens.css via var() — no hardcoded
     theme colors here. The few rgba(255,255,255,…)/#fff values
     are structural highlights (shimmer, knob), not theme colors.
   - backdrop-filter budget (§7): keep ≤ ~8 blurred layers on
     screen at once — nav + a handful of panels is the norm.
   - Hit targets ≥ 40×40 px (§9); visible focus rings everywhere.

   an element cannot replay its entrance however the visitor
