/* ───────────────────────────────────────────────────────────────────────────
   Self-hosted Inter (latin) with metric overrides.

   Inter's native vertical metrics sit the glyph high in the em-box, so text
   reads "pulled to the top" inside tight single-line containers (buttons,
   badges/pills). Re-declaring the face with ascent/descent/line-gap overrides
   re-centres the glyph app-wide. The Google Fonts <link> now loads only
   Plus Jakarta Sans; Inter is served from /static/fonts so these overrides
   are authoritative. Latin subset only (English UI).

   Tuning: text HIGH in tight containers (buttons/badges) → raise ascent-override
   a few %; text LOW → lower it. Centered when ascent-override − descent-override
   ≈ Inter's cap-height (~0.727). Headings use Plus Jakarta, so this only affects
   Inter (body, buttons, inputs, badges).
