+## Fist Detection
+
+`isFist` is computed in `src/lib/handTracking/browserHandTracking.ts` (`isFist()` function) from landmarks alone — no model, no glove. The check is:
+
+1. Palm center = mean of landmarks `[0, 5, 9, 13, 17]` (wrist + 4 MCPs).
+2. Palm size = distance from wrist (landmark 0) to middle MCP (landmark 9).
+3. For each of the four fingertip landmarks `[8, 12, 16, 20]`, check whether its distance to the palm center is less than `1.05 × palmSize`.
+4. `isFist === true` iff all four fingertips pass the check.
+
+The flag is attached to each hand on the snapshot at the publish step (`isFist: isFist(normalizedLandmarks)`) and read directly by `GrabbableObject.tsx` — the SVG visualizer and the 3D glove never participate in the gesture decision.

 The current debug UI includes:
 
 - `HandTrackingDebugPanel` inside `DebugOverlayLayout` for status, usage, loaded glove model, server state, hand count, and fist state
-- `HandTrackingVisualizer` for the SVG landmark overlay
-- `HandTrackingFallback` for the last-resort hand silhouette overlay
-- `HandTrackingGlove` for the per-hand rigged glove models in the R3F scene
+- `HandTrackingVisualizer` for the SVG hand silhouette overlay (always on when tracking is active)
+- `HandTrackingFallback` for the last-resort hand silhouette overlay (legacy, see below)
+- `HandTrackingGlove` for the per-hand rigged glove models in the R3F scene, opt-in via the **Show Model** toggle
 - `r3f-perf` for render performance
 - `lil-gui` for scene, camera, lighting, interaction, and grab controls
 
-The SVG visualizer uses a "blueish hand" style: white connection lines between landmarks, cyan circles with a dark blue outline. The outline gets thicker when the hand is detected as a fist, so the user gets a visual confirmation of the grab gesture without having to look at the debug panel.
+### SVG Visualizer
 
-The fallback overlay (`HandTrackingFallback`) draws a simple open-hand or fist silhouette positioned on the detected wrist landmark. It only renders for a hand whose matching glove is in the `"error"` state in `useHandTrackingGloveStatus`. This guarantees the user always sees something on their hand even when the 3D glove model fails to load.
+`HandTrackingVisualizer` is the primary hand visualization. It draws a light-blue hand silhouette with a crisp dark-blue outline by:
+
+1. Filling a palm polygon (landmarks `[1, 5, 9, 13, 17]` plus two synthetic wrist corners) and five finger tubes (thick rounded `stroke` along each finger's joint chain).
+2. Wrapping the whole thing in an SVG `<filter>` that uses `feMorphology` to dilate the merged alpha by 2 px and subtract the original, producing a single continuous outline around the union — no internal seams where the palm and finger tubes overlap.
+3. Shrinking every landmark toward the hand centroid by `RENDER_SCALE = 0.65` so the silhouette stays compact and doesn't dominate the screen.
+4. Overlaying the 21 raw landmarks and 21 bones as faint translucent lines and dots, so the user can still see the MediaPipe data feeding the silhouette.
+
+The SVG only displays when MediaPipe is active and the debug **Show Model** toggle is off (default). When the toggle is on, the SVG hides and `HandTrackingGlove` takes over.
+
+### Show Model Toggle
+
+The `Hand Tracking` debug folder exposes a single visualization switch:
+
+- `showHandTrackingModel = false` (default): SVG visualizer renders, 3D glove is not mounted at all.
+- `showHandTrackingModel = true`: SVG visualizer hides, 3D glove gets mounted for the detected hand(s).
+
+The 3D glove is treated as opt-in legacy because it had bugs (WebGL context loss, finger rig artefacts) and its hit/grab role was never load-bearing — grab has always read landmarks directly.
+
+### Fallback Overlay (legacy)
+
+`HandTrackingFallback` draws a simple open-hand or fist silhouette positioned on the detected wrist landmark. It renders for any hand whose glove is in the `"error"` state in `useHandTrackingGloveStatus`. Now that the glove is opt-in and rarely mounted, the fallback effectively only fires in the rare case where the user enables `showHandTrackingModel` and the glove fails to load. It is kept on disk for that edge case but is not part of the default visual path.
 
 ## Glove Models
 
+The 3D glove is **opt-in** via the `Show Model` debug toggle (see UI And Debug). It is not mounted by default; the SVG visualizer is the primary hand UI. The information below applies only when the toggle is enabled.
+
 `HandTrackingGlove` loads `public/models/gant_l/model.gltf` for both hands. The right hand applies `scale.x = -1` at the group level to mirror the mesh, so the thumb ends up on the correct side. Both hands therefore share the same rig and the same material.
 
 The historical `public/models/gant_r/model.gltf` is kept as legacy but is not loaded by the frontend — its GLB embeds three skeletons (`Hand_l`, `Hand_l_pad`, `Hand_r`) plus a `galet` mesh, which made the finger rig unreliable.

 - The right glove is a mirrored copy of `gant_l` rather than its own mesh; in the future a dedicated right-hand model would give a better visual.

+- mounts a small "cocoon" decor pass inside (subtle grid floor + soft directional light + ambient) that fades in once the bubble is mostly grown
+
+`Environment.tsx` and `GameStageContent.tsx` consume the same store flag to unmount the vegetation system and the zone debug visuals while the bubble is up, so trees and gizmos do not pierce the shroud. Terrain, water, sky, clouds and grass remain visible behind the bubble.
+
+The bubble is mounted both in `GameStageContent` (production scene) and `TestMap` (physics test scene) so the behaviour matches in both contexts.
