# Deep clean script — supports platform filtering

# Usage:
#   bash scripts/clean.sh                   # clean all platforms (default)
#   bash scripts/clean.sh android           # clean Android only
#   bash scripts/clean.sh ios               # clean iOS only
#   bash scripts/clean.sh macos             # clean macOS only
#   bash scripts/clean.sh windows          # clean Windows only
#   bash scripts/clean.sh android ios       # clean multiple platforms
#
# Via melos:
#   melos run clean:deep                    # all platforms
#   melos run clean:deep -- android         # Android only
#   melos run clean:deep -- ios macos       # iOS + macOS
