+## Character model rollout and rollback
+
+Healer characters use the modular `Rig_Medium` renderer by default. Version 1 composes
+head, upper body, lower body, headwear, back item, main hand, and offhand slots while
+continuing to use Aelia's shared animation set.
+
+Load a hunter, then open **Appearance Lab** from the main menu. The upper display shows
+the real in-game healer renderer with idle, walk, and cast previews. The lower display
+selects healer class and cycles every available part. **Save look** persists the current
+class, **Reset** restores its authored default, and **Cancel** discards drafts. **Compare
+legacy** shows the previous whole-character model without deleting the modular selection.
+
+Some source assets currently fuse related pieces, so version 1 exposes honest combined
+slots such as face + hair, shirt + arms, and pants + shoes. These can split into finer
+customization slots when compatible rigged assets are added.
+
+The previous whole-GLB renderer remains intact during rollout. Use either rollback:
+
+```text
+?characterModels=legacy
+VITE_CHARACTER_MODEL_MODE=legacy
+```
+
+The query changes one browser/app launch. The environment variable produces a legacy
+build. Remove the switch to return to modular rendering.
