/* PONDUCK — the landing page.
 *
 * The same two components as the HUD — a bordered card with a hard offset
 * shadow, and a small tab riding on its top edge — at a larger size. It is the
 * same object because the landing page and the game are the same product, and
 * two card styles in one product is how a page starts feeling bolted on.
 *
 * ⚠ It sits OVER the live 3D scene at 0.86 alpha, so every card needs its own
 *   opaque background. A card that inherits transparency has a lawn moving
 *   behind its text.
