/* ============================================================================
   IC hero scene — live DOM replacement for /video/hero-*.{webm,mp4}
   Plan: ##_plan/2026-09-29_InstitutionalCharts_HeroMotionRebuild_v1.md

   Colours are the application's own design tokens, resolved from
   00_src/frontend-v10/design-tokens.css + vpi-dashboard.css.

   Grid structure follows the application: one class per column applied to the
   header cell and the body cell alike (vpi-dashboard.js:1285), 2px slate rules
   on every cell (vpi-dashboard.css:1196-1197), and centre alignment only on the
   market, tier and energy columns (vpi-dashboard.css:825-831, :1488-1494).

   Motion contract (tripwire T4): only `transform` and `opacity` are ever
   animated. Anything that looks like a width change is scaleX on a child.
