/* ============================================================================
   FEED — Support Tools Library Monitor
   Enterprise activity stream. Theme-aware: reads the shared design tokens set by
   themeEngine (--panel/--panel2/--text/--muted/--border/--accent/--accent-rgb/
   --radius/--shadow), so it adapts to APEX (dark) and Bright Board (light) with
   zero JS. Gold/brand (--accent) is reserved for brand + primary actions;
   data categories get their own categorical colours (per the Service-Report
   colour architecture — no mono-gold on data).
   ADDITIVE: scoped entirely under .feed-page. Touches no existing selectors.
