   Self-hosted webfonts (Requirement 9: font-display: swap).

   NOTE FOR DEPLOYMENT: the actual webfont binaries are NOT yet committed to
   fonts/ (the directory currently holds only a .gitkeep). These @font-face
   rules reference the expected self-hosted file paths so that, once the
   subset .woff2 files are added to fonts/ as part of the seed-asset step,
   typography "just works" with no further CSS changes. Until then the
   robust fallback stacks in tokens.css (--font-display / --font-body) keep
   the site legible and on-brand. Weights are limited to those actually used
   (body 400/500, display 600/700) to keep the payload small.

   To enable: drop the matching .woff2 files into fonts/ with these names.
