# preview_component_layout

Validate and normalize one bounded Components V2 layout locally. Returns a deterministic outline, recursive counts, aggregate Unicode text length, exact normalized HTTPS link destinations and origins, explicit defaults, mention notification projection, and safety warnings without contacting Discord or persisting content. Supports Text Display, Separator, Container, callback-free link-row nodes, and managed request-row Buttons. A request Button creates only a private bounded broker request after publication and click-time scope checks; local preview grants no origin, ingress, write, or administration authority.
