/* ============================================================
   Scenario selector — shared component for practice-guided.html
   and practice-simulation.html.

   Layout:
   - Modules row: horizontal scroll-snap carousel <768px,
     2-col grid 768–900px, 3-col grid ≥900px.
   - Dots indicator: visible only <768px.
   - Scenario panel: single column <768px, 2 columns ≥768px,
     3 columns ≥1100px.

   Theming: every module card carries `--tint` inline (its accent
   color). All accent-tinted rules read from `--tint`. The component
   intentionally does NOT use the per-mode body --accent var (coral on
   guided / sage on live) — the modules need rainbow-palette identity
   so users recognize them across surfaces.
