Releases are built automatically via GitHub Actions. To trigger a build:

• Stable: Push to master or create a v* tag
• Preview: Push to preview
• Manual: Go to Actions → Android APK Splits → Run workflow

Or download the latest APK directly from Releases.

The GitHub Actions workflow builds release APKs with ABI splits (armeabi-v7a, arm64-v8a, x86_64, universal).
