/* ════════════════════════════════════════════════════════════════════
   SHARED PERFORMANCE DASHBOARD — PerfDashboard.astro
   Forked from the styles.css .dash-* block (legacy /reporting mock) and
   made self-contained: loaded by /reporting (Control Room) and the
   homepage proof embed, neither of which may depend on styles.css.
   Animation start-states are applied by /js/mx/dashboard.js only —
   with no JS this renders the complete settled dashboard.
