Repository rules

• src/ is the editable source of truth.
• Do not hand-edit generated HTML unless there is a documented exception.
• Prefer changing source data and build scripts, then regenerating output.

Build and verification

• Run node scripts/build-site.mjs before finishing.
• Keep Japanese root output working.
• Treat build warnings or audit failures as blockers unless clearly documented.

Localization rules

• Japanese numeric data and section structure are canonical.
• Localized copy should sound natural in the target locale.
• Use common local fitness/gym terminology rather than literal translation.
• Keep slugs and filenames shared across locales.
• Japanese stays at /.
• Korean is generated under /ko/.
• Default unit is kg.

SEO rules

• Update canonical, hreflang, sitemap, OG, and internal language links for locale changes.
• Do not ship localized pages with missing localized title, description, or H1.

QA rules

• Check for untranslated source strings in completed locales.
• Check section/schema drift versus Japanese canonical pages.
• Check broken internal links.
• Keep locale diffs reviewable.

Dependency policy

• Avoid adding new dependencies unless clearly justified.
• Prefer extending existing Node scripts and source structure.
