/* ==========================================================================
   Krovi website: shared styles (tokens, base, nav, buttons, chips, footer, utilities)
   Direction: warm cream paper, an elegant high-contrast serif for headlines with a muted
   italic second line, a clean geometric sans for body text, generous whitespace, dark-bezel
   device frames, small pill chips with a green dot, keycaps. LIGHT is the default; dark is an
   opt-in toggle that is remembered (never chosen from the OS setting).
   No external requests: every font is self-hosted under /fonts (SIL OFL 1.1, licences beside them).
   Type: EB Garamond (headlines, variable wght, roman + italic) / Figtree (body, variable wght) /
   Geist Mono (labels, keycaps, code).
