This manifest covers the 16 that accept foreground and background colours: solid, mediumGray, darkGray, lightGray, darkHorizontal, darkVertical, darkDown, darkUp, darkGrid, darkTrellis, lightHorizontal, lightVertical, lightDown, lightUp, lightGrid, lightTrellis. The three omitted values (none, gray0625, gray125) are pattern-only and do not meaningfully carry colours. Each pattern is paired with five colour families (fg/bg hex pairs). One manifest file expands into 16 x 5 = 80 concrete fixture cases. Axis ordering is alphabetised by ooxml_validate.expand_manifest, so fixture names are `<id>--<color.id>--<pattern.id>`."
