 /**
- * Doc-sync gate: verify every fenced ```mermaid block parses with Mermaid's
- * own parser. Markdown link/type/code gates can say a diagram block exists and
- * is linked, but only Mermaid can catch syntax errors that GitHub would fail to
- * render.
- *
- * Scope matches the Markdown link gate so any Mermaid diagram in repo-authored
- * docs is checked: README.md, README.zh.md, docs/** /*.md,
- * packages/* /*.md, packages/* /* /*.md, examples/** /*.md, AGENTS.md,
- * packages/AGENTS.md, and .agents/skills/** /*.md.
- *
- * Run: `tsx scripts/verify-mermaid.ts`.
+ * Parse every repo-authored Mermaid fence with Mermaid itself. Scope matches the
+ * Markdown link gate. Run with `tsx scripts/verify-mermaid.ts`.
