# Locked worksheet presentation

- Locked grid receives a subtle 6% black shade; text and selection remain readable. Tools, search and formula area retain normal contrast.
- Filename shows a custom drawn padlock and localized Read only badge.
- Pale amber notice sits above the formula bar; formula and grid hit areas shift together by 28 px.
- Typing or double-clicking the locked grid briefly emphasizes the notice; title-search typing is excluded.
- After Play the notice/badge/shade disappear and the original layout and brightness return.
- Native Play-policy checks: 18 passed, including ordinary worksheet editing and Play exit restoration.
- Same blank-cell sample pixel: locked ~240, unlocked 255. Actual Play and Edit images inspected.
- Successful capture uses production sources byte for byte. English layout only; no desktop input.
- Nine guide languages rebuilt. New manifest record validated; historical stale screenshot hashes remain outside this task.
- .NET build passed; final sources compiled in native Unity 6000.0.83f1.
- XERJ unavailable at status check; rg used for current source inspection.
