+ * does not (the #236 gap). Whichever surface reconnects the domain next (#233's Studio/Teams
+ * segment) should import from here.
+ *
+ * `category` was read by `blueprintsPage.ts` but no longer exists on the real desktop
+ * `BlueprintCard` (confirmed live against `develop` — the desktop builder never emits it) —
+ * deliberately not carried over here.
+ *
+ * Team-graph parsing (positions/relationships) is NOT duplicated: a blueprint's embedded team
