Blender camera framing

Use scripts/camera_framing.py when a named subject must be wholly visible in the scene camera. The helper uses evaluated world bounds, the active render dimensions and pixel aspect, and Blender's own camera frame. It does not guess from an object's dimensions or from one generic field-of-view angle.

Read references/framing-contract.md before changing the helper or composing a custom framing transaction.

Choose the correct kind of framing

• Render-camera framing changes a Camera object and works in interactive or background Blender. Use this skill for a render, export, shot, or reproducible camera result.
• Viewport framing changes RegionView3D in one visible VIEW_3D area. bpy.ops.view3d.view_selected requires an area/region override, does not work in background mode, and does not fit the scene camera. Use it only to prepare an interactive screenshot and restore selection afterward.
