Colour emoji came out as the placeholder rectangles their outlines carry (Apple Color Emoji) or as .notdef when the face has no outline at all: nothing read sbix, CBDT/EBDT or COLR. A glyph now asks its face for colour ink before its outline: an embedded bitmap strike decoded to premultiplied RGBA and placed by the strike's bearings the way Skia (and CoreText) places it, scaled to the size the run asks for, or a COLR v0 glyph's layers filled from the font's palette. Faces that carry only colour tables are indexed again: Apple Color Emoji is no longer skipped for being 190 MB (the scan still reads headers and name tables only), and "Segoe UI Emoji" and "Noto Color Emoji" join "Apple Color Emoji" as colour fallbacks, read only for a text that nothing else covers. The png crate decodes the strikes; skrifa keeps shaping, metrics and outlines. Left for later: COLR v1 paint graphs, alpha-only strikes and the SVG and PDF exports (text is outlines there). Tests: 8 cases in the text crate (placement, PNG and raw-BGRA decoding, scaling, COLR layers and bitmaps of the machine's own colour font) and a render case gated on that font; the font-free ones run everywhere. Verified on Windows with Segoe UI Emoji (COLR) and with Noto Color Emoji (CBDT) read from a downloaded file; the sbix path runs through the same code and needs a macOS run to be seen. 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>
