# =============================================================================
# Multi-arch bundling strategy: Install ARM64 and x64 browsers into separate
# isolated directories, then merge into the final Cache/.
#
# This avoids fragile INSTALLATION_COMPLETE marker manipulation and the
# backup/restore dance needed when both architectures share a single cache.
#
# - Chromium & Headless Shell: arm64 and x64 extract to different subdirectory
#   names (chrome-mac-arm64/ vs chrome-mac-x64/), so they coexist after merge.
# - Firefox: Both architectures extract to the same path (firefox/), so only
#   x64 is kept — it runs on Apple Silicon via Rosetta 2.
# - WebKit: Only arm64 is installed (mac14-arm64 for macOS 14/15 compat).
#   Playwright 1.58+ dropped webkit support for mac13.
