Answers "what's in this pack / how much XP": shop items now carry contents (sticker ids / emojis), xp amount, and a fa/en description. Cards are tactile (press-3d), show the artwork + name + a quick hint (item count or +XP) + price, with an owned check badge. Tapping a card opens a detail sheet that shows the full contents (every sticker/emoji rendered), the XP granted, a description, and a Buy button (gold when affordable, "need coins" otherwise). Verified: tsc + next build clean; web rebuilt :1500. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
