- HandoffHelper suggests the 3 nearest public skate spots to the listing as
one-tap DM meetup templates (public data only; never the viewer's location).
- New addressable kind 34967 + useShipmentStatus + ShippingStatusCard: seller
marks shipped, buyer received, either issue. p-tagged so the push service
notifies (added to MARKET_KINDS); d=ship:<listing-d>:<author> so a status
replaces only its author's.
- Honest framing: a self-reported claim, NOT proof - 'received' does not release
escrow; no address stored; parcel photos with an address discouraged.
