Lock length dim to mask tip-to-tip (not oversized bbox), require width
labelAt on axis-left off the wood, smaller font contract, and 90% crop
fill extent. Red before green.
Add pure station/axis math and canvas burn-in for a second calibration
inventory PNG (results.overlayPng). Width stations start 6 in from the
EXIF-oriented photo bottom along the approved length axis (6, 18, … ≤
L−6); length graphic sits on axis-right outside the slab. Clean
inventoryPng and batchApply[cal]=null stay unchanged.
Failing TDD for M2 dimension-overlay copy of the calibration inventory PNG:
width stations every 12 in from EXIF bottom (6, 18, … ≤ L−6), axis-right
length graphic, and Calculate storing overlayPng without touching batchApply[cal].
