# Add project specific ProGuard rules here.
# You can control the set of applied configuration files using the
# proguardFiles setting in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

# Preserve line number information for debugging stack traces, plus annotations
# used by JNA/UniFFI structure layout metadata.
-keepattributes SourceFile,LineNumberTable,*Annotation*

# Hide the original source file name (show "SourceFile" instead)
-renamesourcefileattribute SourceFile

# ==================== Enums persisted via .name/valueOf() ====================
# These enums are stored as strings in SharedPreferences/backups.
