Brand and Design Laws

• muetal — the three laws (hairlines not shadows, mono owns every number, the hand never carries data) and how each is enforced in code
• tailwind-v4-prose-generates-css — law 1’s “the utilities do not exist” is a claim about the built CSS, and source scanning can falsify it

Build and Stylesheet Output

• tailwind-v4-prose-generates-css — scanning turns any utility-shaped string (test names, story titles, prose) into shipped CSS; source(none) plus explicit @source is the only durable fix

Formatting and i18n

• nbsp-testing-library-normalizer — U+00A0 in formatMeasure and Hungarian grouping; why Intl needs explicit useGrouping: true for 4-digit values

Testing

• nbsp-testing-library-normalizer — Testing Library’s default normalizer collapses U+00A0; use getDefaultNormalizer({ collapseWhitespace: false })

Tooling and Shell

• tailwind-v4-prose-generates-css — detection recipe: diff the selector sets across two builds; a docs-only edit that moves the byte count is the signature
• bsd-sed-unicode-escape-gotcha — writing \uXXXX escapes into source files without corrupting them; byte-verify after any tooling write
