The app

Lumber Loader The reactive UI, and where new work lands. Tally mode recommends complete, loadable 720 / 864 / 1008-ft car tallies — three match modes, a balance slider (even spread ↔ fewer packs), and an assisted build that re-ranks by target quantities. Loader mode edits each inventory line with −/+ steppers, solves the full visual car layout, and prints or emails a one-page PDF manifest with customer & order #. Open Lumber Loader
