The plan the lumber aisle should have printed

Type it. Buy the parts. Build it.

Measure a space. Yard returns a cut list, hardware, and shop links — for the hole you actually have.

The size you typed

31.5 × 78 × 16 means 31.5 × 78 × 16. Geometry is deterministic. Grok writes the assembly voice — it does not invent a 36″ closet.

Cut list + hardware

¾″ plywood, screws, shelf pins, a window unit. Nominal retail sizes — not fake geometry.

Shop, then build

BOM with packs, prices, and deep links. Print the plan. Buy the parts. Crafts (Eiffel, arch, bridge) use the same bench.
