/* ==========================================================================
   Krovi website — shared styles (tokens, base, nav, buttons, footer, utilities)
   Visual language: clean minimal black/white, macOS-grade. Glass + blur surfaces,
   hairline borders, soft layered shadows, restrained system type, ONE accent.
   Light + dark via light-dark(); explicit [data-theme] overrides the OS setting.
   No external requests: every font file is self-hosted under /fonts (SIL OFL 1.1, licences beside them).
   Type: Bricolage Grotesque (display, variable wght + opsz) / Geist (body, variable wght) /
   Geist Mono (labels, kbd). Palette: warm paper + ink, one ember accent, plus the six app-theme
   swatches as object colours (tool tiles). Radius/shadow/spacing scales are tokens below.
