a pack of cards. Five signed pressings from the season's set, drawn by HMAC over the day's committed seed on the wheels at /design, each with a print number, a page at /p/{card_id} that unfurls, and a verify URL; the signed manifest at /api/pack/{pack_id} binds the seed commit and the inputs, and a crossed milestone drops a one-of-one in. Instant. Full listing: https://scvd.store/menu/pack. MCP tool: buy_pack.
