lint-scss fails on _post.scss due to missing Sass interpolation in custom property

[KKamJi98]

Description

lint-scss can fail on branches that do not modify _sass/pages/_post.scss because the file currently violates scss/dollar-variable-no-missing-interpolation.

Current line:

--wc-stm-font-family: v.$font-family-base;

Expected by stylelint:

--wc-stm-font-family: #{v.$font-family-base};

Why this matters

This blocks unrelated feature PRs when lint-scss runs, even if no SCSS changes are included in those PRs.

Evidence

• Failed job: lint-scss on PR feat: add pagination to search results #2584
  • https://github.com/cotes2020/jekyll-theme-chirpy/actions/runs/22583465371/job/65421751609
• Error:
  • _sass/pages/_post.scss:130:25
  • Expected variable v.$font-family-base to be interpolated when using it with --wc-stm-font-family

Proposed fix

Update _sass/pages/_post.scss line 130 to use interpolation for the Sass variable in the custom property value.

Closing as requested. Keeping scope focused on #2584 (feat/search-pagination) only.
