Measured entry
efferd-not-found-1
A minimal full-screen not-found page shipped as a shadcn registry block. It composes local Button and Empty primitives, uses lucide-react icons and Tailwind utility and theme classes, and assumes shadcn-style path aliases and utility helpers. The registry also declares radix-ui through its supporting primitives.

What the harness recorded
BARE BUILD
✗ Build failed in 1m 33s error during build: [vite:load-fallback] Could not load <sandbox>/src/lib/utils (imported by src/components/ui/empty.tsx): ENOENT: no such file or directory, open '<sandbox>/src/lib/utils'
Verdict
A solid, narrowly scoped error page for an existing shadcn codebase. It builds and mounts cleanly in the prepared setup and shows no measured accessibility or overflow problems, but it needs a shadcn-style setup and is not portable as a bare component.
Use it if
- You need a restrained standalone error page with clear home and discovery actions.
- Your app already uses shadcn registry primitives, Tailwind theme tokens, and alias imports.
- You want a static error state that fits narrow and wide viewports without custom responsive work.
Skip it if
- You need a navbar component, since this entry is actually a not-found page despite its queue pattern.
- Your product needs working destinations out of the box, because both links are placeholders.
- You cannot adopt shadcn-style local primitives, aliases, and utility helpers.
- You need a compact error state embedded inside an existing layout rather than a full-screen page.
Install
| Declared dependencies | radix-ui |
|---|---|
| Missing on install | none |
| Bare install | fails once the shadcn-style helpers are removed, so it needs that setup |
| Provider | no provider required in the harness |
In a non-shadcn project, add compatible Button and Empty primitives, lucide-react and radix-ui dependencies, Tailwind utilities and border theme tokens, the path alias, and the shared class-name utility expected at the project utils path. Replace the placeholder link targets with real routes.
