/* ==========================================================================
   The Learning Curve - main site home page.
   Loaded from templates/home/index.html.twig via {% block stylesheets %}.

   Plain CSS on purpose - NOT a Tailwind entrypoint. Tailwind v4 emits its
   utilities inside `@layer utilities`, and unlayered rules always beat layered
   ones, so this file's cascade is independent of load order.

   Structure: tokens, then layout primitives (wrap / section / grid), then the
   page's own blocks in document order. Rewritten with the October 2026 content
   pass; the old 19-section stylesheet is gone. Palette is unchanged.
