+-- Friendship / relationship storage. Unlike the JSON-blob tables in this shared
+-- database, a relationship is genuinely columnar, so it gets a normal relational
+-- table (mirror of the Go/GORM `Relationship` model). Owned by the `api` worker;
+-- generated from src/relationships-db.ts (SCHEMA_DDL) — keep in sync.
+--
+-- Exactly one row exists per unordered pair of players: the initiator is the
+-- `requester`, the other is the `target`. `relationship_type` is stored from the
+-- requester's point of view (0 None, 1 FriendRequestSent, 2 FriendRequestReceived,
+-- 3 Friend); the target's projection flips Sent<->Received.
