/* ============================================================
   DOUBLE WING TEK — design system v2 "The Descent"
   Dark industrial / metallic-steel, brand-matched to the
   octopus + twin-tank emblem. Signature UX: scrolling the page
   is a descent — surface light fades to abyss, a live depth
   gauge tracks metres, page bottoms out at 332 m (the record).
