/* ==========================================================================
   Velang Cards storefront, v3 (2026-10-11).
   Owner record: docs/features/cards-storefront/SPEC.md

   THESIS: the deck sells itself once you hold a real card. The page leads with
   the offer, the price and a working card, then answers the buyer's questions
   in the order they ask them. It refuses the feature-card grid and the stat row.
   OWN-WORLD: Velang blue system (approved 2026-10-06). Warm paper ground, navy
   ink, one action blue for every action, the brand's cream speech bubble as the
   only decorative shape, a navy band for the price. Lora headings, Outfit text;
   Noto Naskh Arabic and Readex Pro carry the same roles in Arabic.
   STORY: what it is (A0-B2 Anki deck), proof it works (founder pass, learners),
   what is inside (real counts per level), how to start (3 steps), what it costs.
   FIRST VIEWPORT: headline, one line of facts, price and the buy button on the
   start side; the live card phone inside a cream bubble on the end side.
   FORM: conventional product page, conversion-first, by owner decision
   ("whatever converts best"). The in-phone card keeps the deck's own design.
