Landmark Fit Repair

Bbox and IoU are too coarse for final mascot/logo matching. This skill turns named feature drift into recipe edits.

Landmark classes

• structural_tip: outer part tips and extrema;
• shell_corner: face/shell/rim corners;
• feature: eyes, smile, brows, decals;
• ring: aura center/radius/dots;
• depth_marker: side/back/top thickness markers.

Workflow

1. Define a landmark JSON for the source reference.
2. Detect or render corresponding product landmarks.
3. Compare by name and view.
4. Convert deltas into repair actions: move boundary control point, scale one component, shift feature curve, tune depth, or adjust aura radius.
5. Rebuild from recipe; do not hand-edit final geometry without updating the recipe/manifest.
