/** @type {AppTypes.Config} */

// Secure, minimal default configuration.
//
// This is what a plain production build with no APP_CONFIG produces, so it is
// deliberately locked down:
//   - The local file data source (`dicomlocal`) and the runtime `?url=` sources
//     (`dicomjson`, `dicomwebproxy`) are NOT enabled — they widen the attack
//     surface of a default deployment.
//   - `?customization=` URL loading is OFF: no `customizationUrlPrefixes` are
//     configured, so any `?customization=` value is rejected (and aborts boot
//     rather than silently loading).
//   - `dangerouslyUseDynamicConfig` (the `configUrl` query parameter) is off.
//
// It does not need to "just work" untouched — point the data source below at
// your own DICOMweb server. For a fully-featured setup with every data source
// and customization loading enabled, see config/dev.js (local development) and
// config/netlify.js (the public demo deploy).

  // --- URL-driven customizations (?customization=) ----------------------------
  // OFF by default. To allow loading customization data files from the URL, set
  // `customizationUrlPrefixes` to a map of allowed prefixes. The `default` prefix
  // (no slashes) is used for values with no leading slash; every other prefix
  // must start AND end with a slash and is matched against the leading
  // `/segment/` of the value. Files are fetched and parsed as JSONC data — they
  // are never executed. Example (left disabled here on purpose):
  //
  // customizationUrlPrefixes: {
  //   default: './customizations/',                       // ?customization=ctPresets
  //   '/remote/': 'https://cdn.example.com/ohif-custom/', // ?customization=/remote/siteA
