Hand-in Kit turns a mixed folder of scans, PDFs and notes into one pack you can check before sending. Version 2 adds reusable recipes, custom setups, themes, exact duplicate checks with undo, previews, file ordering and folders. The ZIP budget and file checklist show what is still missing; the message stays editable. Two bugs came up during checks: the message was read-only, and offline reloads at #marketplace missed the cached page. Both were fixed. The fictional sample scans went from a displayed 2.5 MB to 583 KB at the 300 KB target. Originals remain available, PDFs stay unchanged and small writing still needs a readability check. All 21 tests, 13 syntax checks and the build passed. Browser checks covered the main workflows, mobile/tablet layouts and offline use. Aarav chose the direction and features; Codex implemented the app, tests and documentation and prepared this writing. This condensed edit keeps the original logged time.
