vrm-mtoon-stroke-tuner

Tunes and fixes outline stroke weight on VRM avatars whose materials come from the MToon implementation in the pixiv three-vrm library. Walks the loaded model's scene graph to locate MToon materials, records which ones shipped with outlines enabled, switches width measurement from model-space units to a screen-relative share of the frame, applies a width factor through a single setter that supports hiding strokes at zero and bringing them back later, and verifies the result across viewport sizes, pixel ratios and model scales. Use when a VRM character's outlines fatten as the avatar is enlarged or the camera closes in, when stroke weight drifts while zooming, or when outline width must be driven from code or a slider at runtime. Not for outline color or lighting problems, materials that lack the MToon flag, mesh or texture edits, or general camera setup.
