- [x] 1.2 Drop `reference_depth` from `load_depth_metadata()` and change `depth_uniform_scale()` to take the computed reference depth instead of reading it from metadata.
- [x] 1.3 Move the base-shape direction fit into `common/depth.py` as `fit_symmetry_depth_direction()` beside `fit_depth_direction()`, then delete `src/anyimage/operators/cutout_tool/depth_calibration.py`.
- [x] 1.4 Delete `selection_calibration()` from `src/anyimage/operators/cutout_tool/geometry.py` and remove its test.
- [x] 1.5 Drop reference samples farther than `REFERENCE_DEPTH_LIMIT` meters before the percentile and use that limit as the reference when the selection leaves no sample.
- [x] 1.5 Drop reference samples farther than `REFERENCE_DEPTH_RANGE_FACTOR` times the median before the percentile, and return `REFERENCE_DEPTH_BASELINE` when there is no valid pixel at all.
- [x] 1.6 Return the flat canonical direction from `fit_depth_direction()` when no sample is usable, and delete the caller-side `try/except` in plane conversion.
