/* ==========================================================================
   11F (Brooklands) Squadron, RAF Air Cadets

   Design note: follows the look of the 2025 RAF websites (raf.mod.uk and
   recruitment.raf.mod.uk) - night-navy grounds lit by a soft blue and red
   glow, heavy uppercase headlines, small yellow tag labels, photo tiles
   with arrow links, and pale-blue panels set beside photographs.

   The squadron's own touch is the Brooklands banking: a yellow flight-path
   curve that sweeps across the home page hero.
