# ViewNotFound

## Overview

Full-page 404 error view displayed when a route path does not match any
registered route. Composes `SystemMessageCard(tone="info")` with a "404" crest,
a `TriedUrlCallout` highlighting the segments of the typed path that diverge
from the closest matching route, a `SuggestionList(shape="route")` of N-best
scored matches, a `DiagnosticStrip` debug footer, and a `Back` + `Go to home`
actions row.

Theme entry: [ViewNotFound](/v3/reference/theming/keys/ViewNotFound.md)
