CFX UI sandbox

A development surface for the shared primitives in packages/ui. Every page renders real components against fixtures — no auth, no database, no Doppler, no credentials of any kind.

Pages

Each page answers a specific question about a component under conditions a dashboard makes hard to reproduce on demand: an error, an empty result, a slow page, a 400-option list, a 320px viewport.

Running it

Both commands are equivalent here — this package is tagged no-doppler, so doppler-serve runs the plain serve rather than wrapping it in a doppler run against a project that does not exist.

nx serve ui-sandbox
nx doppler-serve ui-sandbox

Where this runs

Deployed from main by the same SST + OpenNext CD the dashboards use. A per-PR pr-<N> stage is also deployed on any PR that touches it, on the raw CloudFront URL — those are the previews, and they are why this app is called a sandbox rather than one.
