/* ==========================================================================
   KODAIR WIND — HOLDING PAGE
   TN Media · 2026

   · Type    Montserrat — the family kodairwind.com already uses.
   · Colour  Navy #000061 and turquoise #43CEDD, sampled from the Kodair
             logo and the existing site's buttons.
   · Form    Square. Full-bleed footage, a flat scrim only where the type
             sits, heavy weights. No cards, no pills, no pulsing.
