/**
 * The view-path interfaces below are augmentation points: a plugin adds its
 * own views by merging into them, which widens `AuthView` / `SettingsView` /
 * `AdminView` accordingly.
 *
 * Built-in plugins augment via the relative specifier (`"../../lib/view-paths"`).
 * Third-party plugins target the published subpath, which resolves to this
 * same module:
 *
 * ```ts
 * declare module "@better-auth-ui/core/lib/view-paths" {
 *   interface SettingsViewPaths {
 *     cart?: string
 *   }
 * }
 * ```
 *
 * Without that subpath the interfaces are only reachable from inside the
 * package, so external plugins have to cast their view keys even though
 * `<Settings>` and `<Admin>` already merge every plugin's `viewPaths` at
 * runtime.
