- The Diagonal crop overlay was offered but drew nothing. Guides are now polylines from one
testable module (panels/crop_overlay.rs): thirds, grid, golden ratio, 45° diagonals, harmonic
triangle, golden spiral; triangle and spiral mirror (view.cropOverlayOrientation).
- While cropping: O cycles the overlay, ⇧O its orientation, A locks the crop's current shape
or unlocks it (crop.aspect "current" / "toggle", no refit). Crop panel lists all overlays.
