/* ============================================================
   LANDING PAGE: SEPTEMBER CHROME (2026-10-13)
   Header, bottom bar, pager, Underground tab, huts and hero exactly as on
   27 September 2026 (values from bunkrosnexus.css), undoing the newer shell.css
   layer for this page only. Kept from today: the travelling pulse on the header
   line and on the top line of the phone bar, and the slim menu.
   Loaded only when the page sets $septShell = true (index.php).
