Port of https://github.com/yanliudesign/mono-color-skill (MIT, 2.9k
stars in 3 weeks). Generates original one-ink or controlled two-ink
editorial print images (risograph/duotone/monochrome poster aesthetic)
driven by machine-readable design-system catalogs: substrate/ink
palettes, composition geometry, typography roles, rhythm, controlled
imperfections — all vendored verbatim as the source of truth.
Upstream 34 KB SKILL.md restructured into a hub (143-line core + three
references). Image generation rebound to image_generate; hardcoded
'~/Desktop/Claude skills' path replaced with a neutral output dir.
Upstream examples/ are all-rights-reserved (ASSET-LICENSE.md) and are
NOT vendored — MIT text + catalogs only, with a NOTICE. optional-skills/
placement.
