// Team key: all documents in the team

// Common mistake: using personal key for team operations
// Results in 403 Forbidden on team resources

// Usage
app.delete("/api/documents/:id",

SSO Setup (Enterprise only):
1. Navigate to Organization Settings > SSO
2. Select your OIDC provider
3. Enter:
   - Client ID (from your IdP)
   - Client Secret (from your IdP)
   - Issuer URL (e.g., https://login.microsoftonline.com/{tenant}/v2.0)
4. Configure redirect URI in your IdP:
   https://sign.yourcompany.com/api/auth/callback/oidc
5. Test with a non-admin user first

Supported providers:
- Google Workspace
- Microsoft Entra ID (Azure AD)
- Okta
- Auth0
- Any OIDC-compliant provider

Once enabled, team members sign in via:
https://sign.yourcompany.com/sso/{organization-slug}
