   slide-types.css — SRS Slide Types, Layouts, and Components
   ==========================================================================
   All 15 SRS slide types, 11 layout classes, and 10 component classes.
   Uses CSS custom properties exclusively for visual values — no hardcoded
   colours. Themes provide tokens; this file provides structure.

   Dependency: animations.css and grid-system.css should be loaded first.

   Naming convention:
   - .slide.<type>            Slide-level styling (background, grid, sizing)
   - .layout-<name>           Reusable layout patterns
   - .<component>             Reusable content components
