   TRAINING UI SYSTEM — CLEAN DASH SYSTEM
   Purpose: One organized global CSS file for Training / Learning Center pages.
   Notes:
   - Uses CSS variables for light/dark mode.
   - Uses dash-* components as the current system.
   - Removes legacy component dependencies, duplicates, red test CSS,
     hard-coded list colors, and conflicting repeated overrides.
