lux cloud scaffold

auth, devices, spectra, jobs, and preorders are online.

Lux Cloud is wired for Supabase SSR, magic-link auth, protected spectrum records, queued processing jobs, and preorder intake. The first production path is intentionally small: collect clean scans, keep calibration metadata, and hand expensive work to cloud workers when the node should stay light.
