Design systems and style guides
Each system below informs the ContentRX content model. Role badges show how: standard influences means the system is cited on one or more of the 47 standards; examples corpus means before/after pairs live in the committed examples corpus; moment weights means the system is named in moments.py's weighting philosophy.

Open-source repositories
20 public repositories on the ContentRX content-mining allow-list. The miner extracts before/after pairs from commit history — see external_signal for pipeline details. Each repo's quality signals indicate the presence of a content designer, active i18n, or a content- design blog — proxies for the care taken with content.
