# clean-start.sh - Clean startup script for Early Reader
# =============================================================================
# This script kills all existing development processes, clears caches,
# and starts a fresh development environment.
#
# Usage:
#   ./clean-start.sh [mode] [--full]
#
# Modes:
#   start   - Start Expo development server (default)
#   ios     - Build and run on iOS (skips pod install)
#   android - Build and run on Android
#   tunnel  - Start with tunnel for remote devices
#
# Options:
#   --full  - Full rebuild (clears Xcode derived data, runs pod install)
