   MailCull site chrome — shared public header + footer
   v1.0 — 2026-06-10

   One header, one footer, every public page:
   /, /tools/*, /pricing, /blog(+posts), /help, /contact,
   /privacy-policy, /terms-of-service.
   NOT for: /dashboard, /jobs, /account, /single-check, /admin*,
   /login, /register, OAuth/API system pages.

   In production this is injected server-side: pages carry the
   `<!--site:header-->` / `<!--site:footer-->` markers and
   src/views/siteChrome.js renders the .mc-header (with the drawer) and
   .mc-footer into them, alongside this stylesheet + site-chrome.js
   (dropdown keyboard support, drawer, scrolled border, body scroll lock).

   The kit's `@container` rules were converted to `@media` here because the
   chrome spans the full viewport on a real page, so NO `.mc-viewport`
   wrapper is needed. Auth-aware: the server sets data-auth="in" on
   .mc-header to collapse the right side to a single Dashboard button
   (default is logged out). Tokens only, no new colors, fonts, or radii.

   Every var() carries a literal fallback (the design-system.css base
   values) because the chrome is injected into pages that may NOT load
   design-system.css — the landing page defines its own aliased tokens
   (--r-card, not --radius-card), so without fallbacks the header and
   dropdown lose radius/shadow there. Keep fallbacks in sync if the
   design-system base values ever change.
