 * Restyled 2026-09 to the `Helio Stitch Auth v4` comp: the same dark
 * (`#0C0D0F`) / lime (`#B6D84A`) system the lander (`web/static/lander/`)
 * already ports, rather than the old warm-paper "Hoop Template" identity —
 * DESIGN.md's split between the app's cool acrylic chrome and a warm public
 * face no longer holds now the public face itself is this dark system.
 * Nothing in `frontend/src` reads these tokens and nothing here reads the
 * app's; the two remain separate on purpose.
 *
 * Hand-written, no build step. Bricolage Grotesque + IBM Plex Mono load from
 * Google Fonts, matching the lander's own choice (see its `index.html`) —
 * once that dependency exists for the public site, duplicating it as a
 * self-hosted subset here bought nothing.
