/* ==========================================================================
   SeasonStudio website - design system

   Hand-written static site. No build step, no framework, no CDN. This file is
   a sibling of the SeasonEngine site's assets/css/site.css: it deliberately
   keeps the same se-* class names so both sites share one layout skeleton,
   and changes only the design tokens plus a handful of st-* components.

   Conventions:
   - This whole studio/ folder is self-contained so it can be copied verbatim
     to produce a localized mirror. Nothing here reaches outside studio/.
   - Studio root pages (index.html, 404.html) reference assets as  assets/...
     Pages one folder deep (tools/, guide/, models/, roadmap/) use ../assets/...
   - Every page is self-contained: copy the closest existing page and edit the
     content. Header and footer markup is duplicated on purpose.
