Eric asked what the ↑↓ buttons did — the honest answer was "reorder a
flat list that no longer exists, and fragment your wall diagram if
pushed across a row boundary" (A1, B1, A2 renders as THREE rows under
the letter-grouped layout). The useful half survives as ← → "move
within its row"; the endpoint clamps at row-letter boundaries so the
diagram can't fragment. Tests pin both the clamp and the legitimate
within-row swap; the acceptance flow's reorder step updated to match
the new semantics.

Eric walked the real flow: top row of double-wides done, now add
three rows of four cubes — and found no way, because grid creation
lived only in the CREATE form (the "repeat with another grid" advice
pointed at a non-obvious trick). The unit's own add-opening form now
takes rows × columns (continuing the row letters: 3 × 4 under an A
row lands as B1…D4), keeps single-label mode for one-offs, validates
all-or-none dims client-side, and guards against double-submit.
Also restored: Library Kallax. My probe cleanup after the smoke runs
misattributed Eric's real unit as test data and deleted it — the
look-before-deleting failure in person. Rebuilt with the intended
geometry (two 26.5" double-wides, zone oversize) and the twelve
cubes, committed as his data.
