/* TAPsignal · COSMETIC SHOP · v95.56 (F-02 fix)
 *
 * Closes the Echoes consumption loop. Three placeholder items:
 *   · NEON BLOB SKIN       · 5,000 ◆ · cosmetic
 *   · GLITCH AUDIO PACK    · 8,000 ◆ · cosmetic
 *   · +5 CONTINUE BUNDLE   · 1,000 ◆ · consumable
 *
 * No skin-render path is built yet (v1.1 work). The shop's job in
 * v95.56 is to CLOSE THE LOOP · player earns Echoes → goes to shop →
 * spends Echoes → sees "+1 unlocked" toast → balance decreases. The
 * chase target now visible AND reachable.
 *
 * Surface:
 *   .shop-btn      · button on the intro overlay strip (sits in the
 *                    same row as the streak badge)
 *   .shop-backdrop · modal · radial gradient over stage · matches
 *                    the cymatic aesthetic
 *   .shop-card     · 3 buttons inside the modal
