// This is the entry point of Sentry's frontend application. Want to
// understand how app boots? Read on!
//
// 1. Load the `bootstrap` and `initializeMain` functions
//
//   a. Execute and wait for `bootstrap` to complete.
//
//      Bootstrapping loads early-runtime configuration. See the
//      client_config.py backend view for more details.
//
//      Bootstrapping will do different things depending on if the app is
//      running in SPA mode vs being booted from the django rendered layout
//      template.
//
//      - SPA mode loads client-config via a HTTP request.
//      - Django rendered mode loads client-config from a window global.
//
// 2. Once the app has been bootstrapped with the client-config data we can
//    initialize the app.
//
//   a. The locale module will be initialized using `initializeLocale`. See this
//      function in app/bootstrap/initializeLocale to understand the priority
//      for how it determines the locale
//
//      This also handles lazily loading non English locale files if needed.
//      There is no English locale file as our locale strings are keyed using
//      the English strings.
//
//   b. Call `initalizeApp`, which starts most everything else
//
// 3. App initialization does the following...
//
//   a. Initialize the ConfigStore with clinet-config data.
//
//   b. Setup the colorscheme event handlers, for matching the system
//      colorscheme.
//
//   c. Initialize the Sentry SDK. This includes setting up integrations for
//      routing and tracing.
//
//   d. The <Main /> component is rendered. See step 4 for more details.
//
//   e. Run global init-queue tasks. These are essentially functions registered
//      in the `window.__onSentryInit` array from outside of the app. This is
//      specifically for old-style pages rendered as django templates, but
//      still need React frontend components.
//
//      This also includes exporting some globals into the window.
//
// 4. Once the app is fully initialized we begin rendering React components. To
//    understand the rendering tree from this point forward it's best to follow
//    the component tree from <Main />
//
//    For a quick overview, here's what most render trees will look like:
//
//    <ThemeAndStyleProvider>  <-- Provides emotions theme in context
//    |
//    <Router>                 <-- Matches URLs and renders nested views
//    |
//    <App>                    <-- The App view handles initializing basic
//    |                            parts of the application (such as loading
//    |                            your org list)
//    |
//    <OrganizationDetails>    <-- Most routes live within the
//                                 OrganizationDetails, which handles loading
//                                 details for the org, projects, and teams.
//
