   Color Scrims — RETIRED (2026-07-14, Material "replace the
   computational layer" Phase 5)

   Used to declare a computed 7-step (0-6) alpha-scrim ramp per family
   (--a-{family}-N-tint-scrim / -shade-scrim / -scrim, 189 tokens total)
   — a fixed-hue, parabolic-chroma, increasing-alpha overlay ramp per
   family, consumed by three places: surfaces.css's `--a-canvas-N-scrim`,
   semantics/aliases.css's `--a-scrim-*` role names, and the old
   Phase 1-3 material-bridge.css's `-container-low/-high` aliasing.

   All three were re-routed to the static `--md-sys-color-{fam}-scrim-
   weakest..strongest` ladder (material-static.css already ships this
   shape) as part of Phase 5's full-file sweep — surfaces.css and
   semantics/aliases.css now read the static ladder directly, and
   bridges/material-bridge.css was already retired in Phase 4. A repo
   grep confirmed zero other consumers of any `--a-{family}-N-{tint-
   shade-}scrim` token exist, so this file's own declarations are dead
   and were removed rather than left computing values nothing reads.
   No longer imported by colors/index.css.
