What

Valid custom-font CSS no longer fails lint when an unquoted font-family is the final @font-face descriptor and omits its optional semicolon.

Why

The declaration matcher includes the closing brace in the family name. A declared ProjectFont becomes projectfont}, producing a blocking font_family_without_font_face error.

Same input through the real HTML linter:

CSS declaration	Before	After
@font-face{src:local('DejaVu Sans');font-family:ProjectFont}	1 error; strict-render gate blocks	0 errors; gate permits
Same declaration with a final semicolon	0 errors	0 errors
Quoted family, no final semicolon	0 errors	0 errors
No declaration	1 error	1 error

Chrome 152 CSSOM accepts the semicolon-free declaration as ProjectFont. The issue contains a complete, asset-free reproduction; this comparison exercises lint and the strict-render decision, not a full video render.

Related work

Fixes #6083.

#1538 strips braces from CSS comments; #2538 handles !important. Closed #2778 does not change this declaration extractor.

How

Stop the existing family-value matcher at }. Add regressions for single-word and multiword names and document the accepted syntax.

Test plan

• Two new regressions fail on the base implementation.
• Font rules and project-lint suites: 100 passed.
• Lint package build and TypeScript check passed.
• Real linter/strict-gate before/after and browser CSSOM inspected.
• Changed TypeScript passes oxlint and oxfmt; diff whitespace check passes.
• Documentation updated; comment checks run before push.
