/* ============================================================================
   site.css — shared chrome for every bwee.app marketing page.
   Replaces the per-page duplicated inline blocks (fonts, tokens, base reset,
   nav, footer, download CTA, wrap container, one mobile breakpoint).
   Page-specific styles (hero sizing, pillars, pricing cards, faq accordion,
   compare table/widget, about features/triptych, examples grid, demo) stay in
   each page's own inline <style>, which loads AFTER this file and can override.
   Served at /site.css (copied verbatim by build-site.sh). Absolute /fonts/ +
   root-relative links so it works identically from /, /docs/, /examples/.
