	Use:   "lint",
	Short: "Static checks for operator UI integrity (M7f.1)",
	Long: `lint walks the Go source under internal/server/ and the templates
under internal/embeds/templates/ and reports:

  - dead routes:           routeURL patterns with no registered handler
  - dead swap targets:     hx-target="#X" with no matching id="X"
  - stale tab references:  ?tab= was retired in M7d (operator-mpa-conversion)
  - banned literal URLs:   interpolated hx-* URL strings must use routeURL

Exits 0 on a clean tree, 1 on violations, 2 on internal errors. Safe to wire
into CI or a pre-commit hook. See status/milestones.md (M7f.1) and
docs/operator-ux-conventions.md §9.`,
