/* FairwayFinda Caddie — V3 · 3D ONLY
 * One app, many courses: a selector screen in front of the V2-21 hole engine.
 * The hole is pure-black sunlight (it sits under a rendered course). The SELECTOR
 * is a public brand surface — a golfer reaches it from fairwayfinda.com — so it
 * wears the LANDING's kit: Inter black uppercase, the gold wordmark, the glass card
 * system and the per-section accent tokens. Where the two disagree, the landing wins. */

   V3 — THE FRONT DOOR: THE COURSE-SELECT SCREEN

   ALWAYS the first screen. A golfer arrives from the Course Finder card on
   fairwayfinda.com, so this is a public brand surface and the first thing he ever
   sees of the product.

   The bar is a PREMIUM SPORTS TITLE'S COURSE-SELECT SCREEN, not a settings menu.
   The course fills the screen as its own measured aerial; its name is display type;
   its spec sheet ends on the number nobody else can print — how many trees we
   MEASURED. Picking a course is a moment: the hero crossfades, the type re-sets,
   the numbers land.

   Dark AND luminous. The failure being corrected is a black void with no light in
   it, so the light here comes from the aerial itself, a vignette that frames it,
   gold, and the course's accent — never from adding more black.
   Transform/opacity only: it has to hold 60fps on a phone.
