/* ─────────────────────────────────────────────────────────────────────────────
   Digital One Foundation · The Project Handshake — long-form stylesheet.

   Extends the tokens on digital1.foundation/ rather than restating them, so the
   articles and the homepage stay one design. Shared across every paper and
   cache-busted with ?v=N, following the digital1.one/blueprints precedent.

   The vhost CSP is `default-src 'self'` with `font-src 'self'` — no CDN, no
   external font, no external image. Everything here is same-origin or a data:
   URI, and the six woff2 faces already on the box are the only faces available.
