/* ---------- Self-hosted fonts ----------
   Files live in /fonts/ at the project root. These are the Google Fonts
   variable-font .woff2 files, served locally so the design system has
   no network dependency. Weights 400 / 500 / 600 are pulled from each
   variable font via font-weight descriptors.

     speaks like a coach talking, not a dashboard reporting. JetBrains
     Mono is for anything numeric, code-adjacent, or data-shaped.

       Inter            — UI, body, headings, the wordmark
       Source Serif 4   — editorial pullquotes, hero sub-copy, the
                          "why today" rationale in coaching messages
       JetBrains Mono   — pace, distance, HR zones, timestamps, tokens
