fix(fourier): per-glyph outlines (Space Mono GSUB crash) + real-font test - #12
Merged
Conversation
font.getPath(text) runs opentype.js's shaping pass, which throws "lookupType: 6 … not yet supported" on Space Mono's GSUB chained contextual substitutions — so the Fourier lab silently traced nothing on the deployed site. textToPath now gathers each glyph's own outline (charToGlyph → glyph.getPath) advancing by width + kerning, which never touches GSUB and works for any font dropped into public/fonts. textToPath accepts an injected `font`, and the test suite now parses the bundled TTF from disk and traces three strings through the real pipeline, so this class of failure is caught in CI.

On the deployed site the Fourier lab traced nothing after the Space Mono swap:
font.getPath()throws on a GSUB lookup type opentype.js 2.0 does not implement, andpush()warned and bailed. Outlines are now built per glyph (charToGlyph→glyph.getPath, advance + kerning), which never runs the shaping pass.textToPathtakes an injectablefont, and a new test parses the bundled TTF from disk and traces "POIETIC TECH" / lowercase / punctuation through the real pipeline so CI catches this.
