stylelint-plugin-font

stylelint-plugin-font is a Stylelint plugin focused on font-loading quality, @font-face correctness, and performance-oriented fallback hygiene.

The repository uses a modern Stylelint plugin architecture with typed rule modules, statically authored rule metadata, and shareable config exports.

What the package currently exports

• A default Stylelint plugin pack export.
• A plugin-scoped shareable config map: fontPluginConfigs
  • font-recommended
  • font-all
• Static runtime metadata and typed helper infrastructure for future rule authoring.

Current rule status

The public rule catalog includes 18 font-focused rules.

Current rule families cover:

• required @font-face declarations
• src order and format preferences
• duplicate/consistency checks across font-face blocks
• fallback and deployment safety checks in normal selectors

What comes next

Future public rules can continue extending font-quality concerns such as:

• stricter optional variable-font migration detection
• locale/subset guidance beyond unicode-range presence
• refined fallback stack policies per project profile

The package surface is intentionally curated: the goal is high-signal font guidance, not duplication of generic CSS lint rules.
