Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
jp-web-design-guardrails
Guardrails for building Japanese-ready web interfaces. Automatically enforces correct CJK typography (font stacks, line-height, kinsoku shori), Japanese form conventions (furigana fields, postal code auto-fill, Imperial era dates, confirmation screens), honorific-aware UX copy, seasonal color themes, accessibility (JIS X 8341-3), and production-ready CSS. Prevents common mistakes like using italic for emphasis, wrong name field order, and loading full CJK font files.
