/* ============================================================================
   The public blog — /blog and /blog/<slug>. Built by scripts/build_blog.py.
   ----------------------------------------------------------------------------
   House scale and palette, literal values (same reason as assets/sitepage.css:
   these pages define no palette of their own). Instrument Sans body, Bricolage
   Grotesque headings, JetBrains Mono for labels and figures.

   Motion follows the homepage contract: every start state is scoped to html.js
   (set before first paint by assets/sitefigure.js), so with no JavaScript the
   finished page is what renders, and reduced motion gets no movement at all.
