/* ARDA — shared site chrome: header, mobile menu, footer, booking form.
   Used by every page. Markup lives between the "site-header" / "site-footer" /
   "site-booking" markers in each page and is kept in sync by tools/sync-chrome.py.
   Everything is scoped to .site-* / .booking / .bf-* classes because the legacy
   bundled pages still carry generic `header` / `header nav a` rules.
   Visual direction: "Traust" (strict, precise, accountable). Page content
   styles live in assets/traust.css. */
