User adds one photo taken under Setup. 2. App removes the background and shows a mask overlay on the source photo: slab pixels vs removed pixels. Controls: sheet Auto / Green / Black, one sensitivity slider. Overlay updates as the slider moves. 3. User adjusts until only the slab remains, then approves the mask. That approved mask is the slab footprint for every later step. 4. App draws the minimum-area bounding rectangle of the mask and the length axis on the long side of that rectangle. User rotates the axis if it does not follow the slab length, then approves the axis.
