/* ===========================================================================
   Shared marketing chrome (UX-P5) — the ONE source of truth for the header,
   footer, container widths, buttons and base body styling across every
   aisbom.io marketing page. Linked AFTER _shared/tokens.css so it consumes the
   design tokens. Pages no longer duplicate this CSS in their inline <style>.

   Page-specific layout/visual styling still lives in each page's inline
   <style>; only the cross-page chrome belongs here.

   these tokens while loading a fresh site.css. An undefined var() makes
   max-width invalid → `none` → the whole page goes full-width. The fallback
   keeps the layout correct even when --container-max/--prose-max are missing.
