React Three Fiber

Use this skill when rendering live HTML/DOM elements (or frozen snapshots of them) as PixiJS v8 textures via the EXPERIMENTAL HTML-in-Canvas browser APIs. Covers the pixi.js/html-source side-effect import, feature-detection with canvas.requestPaint, HTMLSource for a live, repainting element kept interactive in the browser (autoLayout/autoUpdate/autoRequestPaint, requestPaint, isReady, the direct-child-of-canvas + layoutsubtree requirement), ElementImageSource for an immutable captureElementImage() snapshot (autoClose, ready immediately), using the source on a Sprite/Texture/Mesh, fallback-only auto-detection via Texture.from at priority -10, and destroy/cleanup. Triggers on: HTMLSource, ElementImageSource, pixi.js/html-source, requestPaint, captureElementImage, ElementImage, layoutsubtree, autoRequestPaint, autoUpdate, autoClose, HTML in canvas, render DOM to texture, HTMLSourceOptions, ElementImageSourceOptions, HTMLSourceCanvas, experimental.
