/* FTF public site -- modest, business-first: light pages, navy brand colour, one teal accent, one
   typeface (monospace for code only). Sentence case everywhere.
   Layout (2026-10-16, FTF Site Layout.md): two panels -- a top navigation bar, always on screen, with
   drop-down menus, and the body (the page, optional tabs at its top). Desktop first; at
   phone width the menu opens as a list from the Menu button. */
