Update, 1 October: Hand-in Kit has a shorter README, a sample walkthrough and links to the full guide. Filename and folder selection now use separate helpers, and theme defaults are clearer. All 21 tests, 13 syntax checks and deployment passed. On the live app, two scans named अभ्यास kept separate References paths; the Lab checklist and Hindi subject also worked. Originals remain available, PDFs stay unchanged, and screenshots use fictional samples. The reviewer’s self-written README and human-code request is still unresolved. Aarav chose the direction; Codex prepared the implementation, tests, docs and this text and ran the checks. This edit retains the original logged time. Demo · Source and guide
