/* ==========================================================================
   Dr Ron Ehrlich — design system v2
   Typography: PP Editorial New (display) + PP Neue Montreal (body)
   Palette: Paper, Ink, Rule, Blush, Oxide

   v2 distinctions vs v1: Library card grid (with hover-to-reveal as the one
   non-obvious interaction), Practitioner block, expanded Book pipeline,
   anatomical hero composition (no typographic-plate hold-position).

   Font loading strategy:
   - Online: PP Editorial New + PP Neue Montreal load from Fontshare CDN.
   - Offline / CDN unreachable: IBM Plex Serif + IBM Plex Sans + IBM Plex Mono
     are self-hosted from /assets/fonts/ as the active fallback. The font-family
     stacks below cascade Editorial New → IBM Plex Serif → system-serif so the
     page renders in editorial type on any connection.
