- Reviews: confirming a trade now lets the reviewer set a 1-10 skateboard-deck
rating, stored as ["rating","n"] on the kind-31871 attestation (NIP.md updated).
The Reputation tab shows each review's decks plus an average.
- New DeckRating component (self-drawn deck glyph) and TradeConfirmRow (rating
picker + confirm), used for both seller-confirm and buyer-confirm in My Trades.
- New 'Selling' tab: your marketplace listings (active/sold) with one-tap
Mark sold.
- /marketplace is now a hub with a sticky tab bar: Browse (the gear grid),
My Trades (existing flow), and Reputation — the trader's reputation score,
peer recommendations, and a Reviews/trade-records list built from kind-31871
attestations (who, sold/bought, method, amount, note, link to the listing).
- Nav: the old 'trades' entry becomes 'Marketplace' -> /marketplace (no longer
auth-only, since browsing is public).
- /trades and /listing/... deep links keep working.
