What to build

The app builds Atlases from Lock snapshots automatically and byte-stably. See User Stories 62, 63, 65 and 66, ADR-0005 and #4.

Acceptance criteria

Layout v1: one row per Look (max 3), columns face → front → side → back, uniform 4:9 cells, fit-and-pad on neutral mid-grey, wider row gutters, no text; missing Tiles collapse their cell; only same-Parity Looks combine
Scaling to a megapixel budget (1.0 MP default, never upscaled) or native, set per Project
Atlases are a cache keyed by a hash of the ordered snapshot IDs, the layout version and size settings; the same key reuses the same Atlas
Atlas pixels are byte-stable for the same inputs
An Atlas preview can be shown for a group of Looks
Golden tests check Atlas bytes or hashes and cache reuse
