+    compact, line-separated list (the owner's density pick over bordered cards). `gameDTO` / FB
+    `GameView` gained `last_activity_unix` (the turn start while active, the finish time once
+    finished). The in-game **"add to friends"** item is now **server-derived** (new `GET
+    /user/friends/outgoing` + `friends.outgoing` op, returning the addressees already requested —
+    pending **or** declined, which both read as "request sent") so it is correct across reloads, shows
+    a disabled **"✓ in friends"** once accepted, and **live-updates** when the opponent answers:
+    `RespondFriendRequest` now publishes `friend_added` (accept) / `friend_declined` (a new notify
+    sub-kind, decline) to the **original requester**, whose open game re-derives its friend state.
+    Owner decisions: a declined request stays "request sent" (non-revealing); an accepted opponent
+    reads "✓ in friends"; rack-tile reorder while tiles are placed stays disabled by design.
