 - [x] Add generic injury state.
-- [ ] Add bleeding placeholder.
+- [x] Add bleeding placeholder. Survival now tracks replicated
+  `BleedingSeverity`, applies lightweight health/exhaustion pressure while
+  bleeding, adds bleeding from generic injuries, exposes add/reduce hooks, and
+  shows bleeding in debug HUD and console survival output.
 - [ ] Add sprain or movement penalty placeholder.
 - [x] Add cold exposure damage.
 - [x] Add starvation damage.
