/* flatping - mobile-first, light, one thumb. The card is the product.
 * Deck card layout ported from flat-radar's site/index.html (full card
 * parity, 2026-10-08): absolute cards in the stage, tap-through photo
 * set with the map as the last frame, back card behind the top one.
 *
 * Landing direction (2026-10-09, "the listing sheet"): the visual
 * language of a London letting notice - paper white, serif display,
 * mono for listing data, hairline rules instead of card grids, one
 * deep green. The purple SaaS kit, gradient washes and shadowed tile
 * grids are gone on purpose; the signed-in deck keeps its own language
 * (physical cards, soft shadows) because there the card metaphor is
 * literal. */
