/* ============================================
   Recipe Collection — Thanksgiving Theme
   Holiday redesign: deep burgundy + burnt orange
   + amber gold accents on a warm cream backdrop.
   Function unchanged. All class names preserved.

   Modern CSS protocols applied (see references/modern-css-protocols-and-styling-2026.md):
   - Cascade layers (@layer) for deterministic cascade management (§5.1)
   - OKLCH perceptually-uniform color with sRGB fallbacks (§3, §9.1)
   - Fluid typography via clamp() (§8)
   - Native CSS nesting (§4.3)
   - Relational :has() enhancement (§5.2)
   - Scroll-driven reveal, guarded by @supports (§6.1 — outside Baseline in Firefox)
   - Public-domain images (CC0) applied via ::before/::after pseudo-elements
     so no HTML markup changes are required.
