Vibe Cam - Moments Never Fade

This update adds a lens chromatic aberration effect, rewrites the film grain generation algorithm, and adjusts the layout of the capture screen. [New] Chromatic Aberration Simulates the lateral chromatic aberration of real lenses: at light–dark edges, one side shifts toward red-orange and the other toward blue-cyan, becoming more pronounced toward the corners of the frame. This is one of the most recognizable optical signatures of vintage lenses, toy cameras, and disposable film cameras. A phone's main-camera ISP usually corrects it away, so here we add it back algorithmically. The implementation uses a radial polynomial displacement model for lateral chromatic aberration, combined with spectrally weighted multi-tap sampling, producing a continuous transition from orange through white to cyan rather than a crude three-color split. Six parameters are provided — Strength, Corner Concentration, Sharpness Retention, Color Purity, Sample Count, and Color Direction — along with two built-in calibrations, "Fringe" and "Lens." Displacement is measured in 12 MP-equivalent pixels, so the editor preview matches full-resolution exports. Chromatic aberration is off by default and can be enabled on the capture screen and in the RAW editor. [Improved] Film Grain Grain noise has changed from white noise to lattice value noise, restoring the clumping of silver-halide grains instead of a uniform, per-pixel fine sand. We also fixed grain size drifting with output resolution: the editor preview and the exported photo now show the same grain scale. Grain amounts for all film presets have been recalibrated, so finished images look the same as before. The grain slider in the RAW editor now spans 0–100 instead of 0–50; the maximum available grain is unchanged, only the scale is finer. [Changed] Capture Screen · The self-timer has moved to the top toolbar, alongside the flash; · The sharpening toggle has been removed; capture now always uses the no-extra-sharpening output path; · Two buttons remain on each side of the shutter at the bottom, in a symmetric, evenly divided layout. [Other] · After switching cameras, photo and video now retain the previous resolution, format, and frame rate wherever possible; · Fixed an issue where changing the image resolution could affect the capture mode and Live Photos; · Rebuilt the settings storage layer for improved stability.
