# API Surface
## Primary Integration Style
The package is intended to be embedded by other Go applications.
Current package shape:
- `viewer.RenderHTML(snapshot []byte) ([]byte, error)`
- `viewer.NewHandler(viewer.HandlerOptions{...}) http.Handler`
- `viewer.NewStandaloneHandler(viewer.HandlerOptions{...}) http.Handler`
Integration model:
- embedding app provides the JSON
- chart renders HTML
- embedded mode does not own snapshot selection UI
- standalone mode may provide a local upload screen on `GET /`
## Expected Runtime Endpoints
These endpoints are expected for the standalone binary only:
- `GET /` - upload page
- `POST /render` - accept one Reanimator JSON payload and return rendered HTML
- `GET /healthz` - basic process health
Embedded handler endpoints:
- `GET /` - empty viewer shell with no upload controls
- `POST /render` - accept one Reanimator JSON payload and return rendered HTML
- `GET /healthz` - basic process health
- `GET /static/...` - embedded static assets
## UI Route Rules
- No multi-product navigation
- No upload wizard with preview/confirm/execute stages
- No collector/API-connect workflow
- No background job polling API
- Embedded mode must not force a file picker into host applications
## Response Rules
- HTML pages are read-only views of one snapshot
- API responses must not modify or augment the input payload semantics
