/* Dasasian — one stylesheet, no build step.
   Type system is deliberately two families: a serif for everything readable,
   a mono for everything that labels. No sans anywhere. */

/* ---------- fonts ----------
   Self-hosted so the site looks the same everywhere. On system stacks alone it
   rendered as Iowan Old Style on macOS, Georgia on Windows and DejaVu on Linux
   — three materially different sites, and typography IS the design here.

   Newsreader is a variable font: one file covers 200-800 plus an optical-size
   axis, so display sizes get a face cut for display automatically.
   Both are OFL — see fonts/LICENSES.md. System fallbacks are kept so a failed
   fetch degrades rather than breaks. The italic only downloads on pages that
   actually use <em>; browsers defer font files until a glyph needs them. */
