From 009ff69ee2d41fbc4ee236bfad36113cdd5fb70d Mon Sep 17 00:00:00 2001 From: Aram Hammoudeh Date: Thu, 2 Apr 2026 20:32:49 -0600 Subject: [PATCH 1/9] feat(platform): add mobile platform support for iOS, Android, responsive scaling, gamepad, and CI Implements five mobile platform issues: - #281: iOS Flappy Bird example with touch/keyboard/mouse input - #304: Android Flappy Bird example with touch/keyboard/gamepad input - #305: Mobile CI with simulator/emulator runtime smoke tests - #306: DPI-aware responsive scaling with safe area insets - #307: Gamepad/controller input via gilrs with
