0.3.0

Added

• Unapplied edits badge: when a <name>.edit.gltf/.edit.glb sits next to the
  displayed model, a small hint appears in the top-left corner of the viewport. Outside
  edit mode the viewer deliberately shows the original — the edit file is a change
  request, not the model — which previously looked as if saved work had been lost. The
  badge appears in all viewing paths (code block, embed, file view) and updates without
  a reload when the edit file is created, deleted or renamed.

Fixed

• Leaving edit mode failed silently. TransformControls.dispose() throws in
  three r169 (this.traverse is not a function — the class moved from Object3D to
  Controls, but its dispose() still calls traverse). The error aborted everything
  that followed it: edit mode could not be left, the viewport stayed pinned so
  auto-rotate and orbit never resumed, and unloading a block never disposed its WebGL
  context. Also hardened: a failing rig teardown can no longer block the exit.
