/* ==========================================================================
   Avid Common UI – Documentation Theme
   ==========================================================================
   Loads after central_style.css and overrides it with a token-based approach.
   Provides full light/dark mode support via CSS custom properties.

   Design principles:
   - Compact, scannable layout — no wasted vertical space
   - Card-based toolkit entries with clear hover affordance
   - Developer-friendly: readable code blocks, clean tables, breathing room
   - Smooth light ↔ dark transitions using Avid Common UI tokens
