Font fixture attribution

sample.otf and sample.ttf are the Regular weight of Source Code Pro by Adobe, licensed under the SIL Open Font License 1.1 (see that repo's LICENSE.md). Both are the same font family deliberately, so tests can assert glyph-count fidelity (1568 glyphs) across otf/ttf/woff conversions of "the same font" rather than comparing unrelated files.

sample.dfont is Tests/ttx/data/TestDFONT.dfont from fonttools/fonttools, MIT licensed. It is a small (3.5KB) fixture containing one real embedded sfnt TrueType resource (7 glyphs) — used to exercise this project's dfont-container extraction code without needing a large real-world font suitcase.
