Bins section now mirrors the grids section with two tabs: - Bins: gallery of processed bin records - Sources: source images tagged with uses=['bin'], with upload and '+ Bin' button to create a bin record from an existing source image Server: POST /api/bins/from-source accepts source_id, creates bin record and adds 'bin' to the source image's uses array. URL state: /bins → bins tab, /bins/sources → sources tab. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
