+# World of Guildhall
+
+WoW Classic–style co-op adventure for Fred's friend group. Stdlib Python server
+(`app.py`), content tables (`content.py`), fight engine (`combat.py`), world
+rules (`game.py`), vanilla JS client (`static/`). The world is one JSON doc in
+SQLite.
+
+## Design rules
+
+- Every ability is auto (rule, AUTO_CD × cooldown) or manual (pressed, real
+  cooldown). Manual only holds while the player is watching (`WATCH`); never
+  let an unwatched player's abilities sit unused.
+- Dungeons are group-only and are where active play matters: tune bosses so an
+  all-auto group struggles (`tools/balance.py dungeon`), trash so it doesn't.
+- Use Classic's names for places, mobs, quests, NPCs and items.
+- In-game text is terse: icons and numbers over prose, details in tips.
+- Every requirement/progress ratio is **have / need** (`3 / 10`).
