# Fetch and Send Data

## Step 1 — Read AGENTS.md

Check **Interactivity Mode** and **Scope**:

| Mode | Data access |
|------|-------------|
| None (Static SSR) | Server-side: inject services/`DbContext`. Use `[StreamRendering]` for loading UX. |

| Auto | Both server and browser. Always go through an API. |
