Release notes for 4.3.0.

Released: 2026-07-19

Syntax highlighting is now driven by semantic design tokens across document code fences and HtmlPreview. Browser previews lazily load the public zfb WASM highlighter, existing color schemes inherit compatible semantic aliases, and project-owned Shiki dependencies and theme-name configuration are no longer required (178f23321)
Home pages can opt into the wide content layout with home.wide; the setting applies consistently to package-owned root and localized home routes (d068ac346)
Doc history can exclude selected pages through configuration, with matching behavior threaded through rendering, history generation, package settings, and generated-project configuration (e18c2e528)
The Hearth theme now provides complete admonition icon coverage (736c6c5e1)

Frontmatter status pills now meet WCAG contrast requirements across every shipped theme pack, light/dark mode, and semantic role while preserving their tinted backgrounds (2986d87c4)
The showcase now consumes the package-owned theme contract correctly and emits literal semantic z-index utilities (2ca79ca6b, 8fb517df6)
Theme-pack font validation is stricter, and the generated setup skill resolves main-worktree paths reliably (f9dd94d53, 4c2a508bb)

Expanded English and Japanese documentation for syntax-token migration, wide home layouts, doc-history exclusions, theme development, and network exposure caveats
Added browser-level highlighting coverage, exact pill contrast checks, settings parity tests, and compatibility-contract guards
