/* public-site/enterprise.css
   The /enterprise landing page's own design layer.

   Loaded AFTER public.css on /enterprise only (page({ head }) injects the
   link). Everything is scoped under body.ent -- the page sets its palette by
   REDEFINING the site's shared tokens (--bg, --ink, --brand...) inside that
   scope, so public.css's global element rules (links, focus ring, selection,
   skip link) follow the enterprise palette without one selector being
   overridden. Enterprise-only tokens carry an --ent- prefix.

   Design school: editorial confidence. Warm paper, near-black ink, one deep
   green accent, serif display type from system faces (this site has never
   loaded a webfont; that record holds). Numbered chapters instead of icon
   grids. Every visual is a captioned exhibit of real product mechanics.

   Breakpoints match the site: 980 / 760 / 520. Dark mode is the same
   prefers-color-scheme block pattern as public.css. */
