 # create-eigen-game
 
+## 0.10.1
+
+### Patch Changes
+
+- [#56](https://github.com/eigeninteractive/eigen-server/pull/56) [`ede5342`](https://github.com/eigeninteractive/eigen-server/commit/ede534238b8c3dac07c4a55f5c7a846ffc2a5aab) Thanks [@seenu-k](https://github.com/seenu-k)! - Scaffold an optional `AUTH_DOMAIN`.
+
+  Web sign-in runs through Firebase's popup, which loads
+  `https://<authDomain>/__/auth/handler`, so Google's account chooser reads "Sign
+  in to continue to my-project.firebaseapp.com". `app-config.json` now carries an
+  `AUTH_DOMAIN` key and `main.dart` passes it to `EngineConfig.authDomain`. The
+  pinned `eigen_flutter` floor moves to `^0.4.1` for that parameter: additive, so
+  a patch pre-1.0, but the floor has to rise or a scaffold could resolve 0.4.0 and
+  fail to compile.
+
+  Empty is the scaffolded value and the right answer for almost every game: it
+  leaves sign-in on the Firebase project's own domain, which works everywhere and
+  needs no Firebase Hosting. Setting it is cosmetic and web-only, and it is not
+  `APP_HOST`: the value must be a Firebase Hosting domain, a sibling of the
+  Worker's host rather than the host itself.

 # @eigeninteractive/server
 
+## 0.3.1
+
+### Patch Changes
+
+- [#55](https://github.com/eigeninteractive/eigen-server/pull/55) [`13ac3e3`](https://github.com/eigeninteractive/eigen-server/commit/13ac3e38ab18a8da39e09392bc3a70226d0b3bf2) Thanks [@seenu-k](https://github.com/seenu-k)! - Serve a placeholder app icon instead of linking one that is not there.
+
+  Every page the engine renders linked `/favicon.png` and `/icons/Icon-192.png`
+  unconditionally. Those are static assets from the game's own `public/`, which a
+  fresh scaffold ships holding a single `.gitkeep`, so until a Flutter web build
+  landed there the browser tab was blank and all four manifest icons 404ed. An
+  Android-only game, which never runs `build:web`, stayed that way permanently,
+  even though the download page's hero already had a fallback for exactly this
+  case.
+
+  The shell now links the EigenInteractive mark, served by the worker at
+  `/_eigen/icon/v1/mark.svg` and drawn in the game's `site.primaryColor`, and the
+  manifest advertises that single scalable icon rather than four missing PNGs.
+  Apple's touch icon is omitted rather than pointed at a missing file, since it
+  has no SVG support.
+
+  It is a placeholder, not a default: as soon as `favicon.png` exists in
+  `public/`, the shell links the game's own icons everywhere and the placeholder
+  goes unused.
+
+  The probe behind that decision was split in two. `hasWebBuild` asks for
+  `index.html` and still gates the "Play on the web" button; the new
+  `hasAppIcons` asks for `favicon.png` and gates every icon. They used to be one
+  question on the grounds that `flutter build web` emits both together, which is
+  true for a game that ships on the web and wrong for the case worth supporting:
+  an Android-only game that copies its launcher icons into `public/` now gets
+  them. `hasAppIcons` checks the response's content type as well as its status,
+  because the scaffold's `single-page-application` fallback answers `200 OK` with
+  `index.html` for any asset that is missing.
