+// Hats — cosmetic supporter hats, worn above the avatar everywhere it shows:
+// chat rows, DMs, profile pages, notes, search results, the header.
+//
+// Ownership lives on the names registrar (a kind-0 field would be
+// self-asserted — anyone could wear anything). Buying is a plain Lightning
+// invoice minted by the registrar and paid headlessly from the Spending
+// balance; the registrar grants on settle, and the sats simply stay with
+// coinos. That's the whole point: a hat is proof you chipped in.
+//
+// Display is a batched lookup (`GET /hats?pks=…`) cached alongside nothing
+// else — one request covers a whole room, answers persist for a few hours.
+// The crown is Adam's and is not for sale.
