/* ═══════════════════════════════════════════════════════════════════
   jasonritz.com — production stylesheet
   ═══════════════════════════════════════════════════════════════════
   ARCHITECTURE
   - Single stylesheet shared across all pages.
   - Per-page theming via body classes (.theme-code/books/work).
   - Three things change per theme: --accent, --texture-image, --texture-blend.
   - Everything else (typography, layout, spacing) is constant — that's
     what makes the sub-pages feel like one site.
