/* ═════════════════════════════════════════════════════════════════════
   PULSE Compatibility — "HRDP data grid / readiness console"
   The searchable game-compatibility matrix in the v3 instrument language:
   near-black canvas, a cyan title channel rule, a monospace search console,
   the matrix as a hairline data grid with sticky mono column headers +
   tabular numerals, semantic status pills, the request CTA as an instrument
   panel. Rows are injected by /js/compatibility-page.js (externalised from a
   CSP-blocked inline <script> that left this page stuck on "Loading…").

   Scoped under .compat-page. Depends on shared.css + tokens-v3.css + bg.css.
