The previous commit left two findings open: in the pixel art tab the palette colour and the opacity of a layer still told the editor about every input, and so did the place fields of the curve tab. They now follow the same rule as the inspector rows. - PixelArtSide writes colour and opacity into the model on every input and requests the preview through a FramePreview. Both commits cancel a waiting preview first. - CurveCanvas.movePicked does the same for the t and v fields of the picked point. Showing another curve cancels a waiting preview. - Also fixed: when the colour picker ended on the colour it started from, the model was put back but nobody was told, so the previewed colour stayed on screen. commitColor now says so, as the opacity already did. The gain was not measured for either tab, only the behaviour is tested. Tests: - Gate: 198 files, 2911 tests (2907 + 4), exit 0 - e2e 47,48,53: 117 checks passed - Four new unit tests in tests/editor/frame-preview.test.ts: colour, opacity, curve fields and the return to the starting colour - Seven counter-probes fail, one test each. They ran on stein2, not in the container. - No new e2e check, the sum stays at 1616. Neither the full suite nor the smokes ran for this state, and there was no counter-probe in the browser.
