/* ciidb site chrome — the header and footer every inner page shares (13.10.2026).
   Same language as the homepage: logo · four rooms centred · members' login; a footer that is the last chance
   to send people anywhere on the site. Applied to pages by scripts/site_chrome.py; edit there, not by hand.
   Namespaced cx-* so it never collides with a page's own classes. The login slot keeps auth.js's .nav-actions. */
