- Fix slow object operations / unresponsive layer panel: 3D pose images no longer embed the VRM model (data-pose3d-model, ~56MB each); existing ones are stripped on page open and on save. Images/balloons/groups are saved only when actually moved.
- Text corner handles now keep the opposite corner fixed and scale in the drag direction.
- Balloon-embedded text can be moved by dragging the triangular corner of a dotted box (double-click opens the existing modal).
- Help (ja/en/zh), README (ja/en/zh) and DEVLOG updated.
