/* ══════════════════════════════════════════════════════════════════════════
   Dashboard (UI-Redesign, 2026-10-22). Channel chips → day section (stat
   cards, messages per hour, top chatters) → month section (KPIs, calendar,
   weekday×hour heatmap, rankings, trend). Every panel is a .dash-card;
   loading dims, never empties (.is-loading); breakpoints inside are
   container queries on .dash-main. Chart intensities are ONE hue (the
   accent) at different strengths. Tokens only; --fs-chart is the
   documented axis-label exception. History: docs/logs-dashboard.md.
