/* ============================================================================
   Sight — GetSight.App design-system stylesheet (adopted 2026-07-24)
   ----------------------------------------------------------------------------
   Single stylesheet for every public static surface. Token VALUES are copied
   verbatim from design/getsight-ds/tokens/*.css (the canonical source). Fonts
   are self-hosted (no CDN, zero external requests). Marketing is the light
   `.theme-light` scope; dark sections opt in with `.on-dark`.

   Discipline (design/getsight-ds/_adherence): every color/space value below the
   token block references a `var()` token — no raw hex outside :root/.theme-light/
   .on-dark, and only the three brand fonts (Schibsted Grotesk, Hanken Grotesk,
   JetBrains Mono).
