# --- Step 1: Install ARM64 browsers for macOS 14/15 (Apple Silicon) ---
# Use mac14-arm64 override instead of native mac15-arm64 so that webkit is
# compiled against the macOS 14 SDK. This binary is forward-compatible with
# macOS 15 but the reverse is not true (mac15 webkit uses symbols absent on 14).
# NOTE: Firefox is deliberately excluded here. Both arm64 and x64 Firefox
# extract to the same directory path (firefox-<rev>/firefox/), so only one
# can exist. We install x64 Firefox in Step 3, which runs natively on Intel
# Macs and via Rosetta 2 on Apple Silicon.
PLAYWRIGHT_HOST_PLATFORM_OVERRIDE=mac14-arm64 npx playwright install chromium chromium-headless-shell webkit
PLAYWRIGHT_HOST_PLATFORM_OVERRIDE=mac14-arm64 npx playwright install-deps chromium webkit

# --- Step 2: Back up ARM64 Chromium files ---
# Playwright deletes the entire browser revision directory (e.g. chromium-1208/)
# when INSTALLATION_COMPLETE is missing. We must preserve the arm64 subdirectories
# before the x64 install wipes them out.
ARM64_BACKUP=$(mktemp -d)

find "$PLAYWRIGHT_BROWSERS_PATH" -type d -name "chrome-headless-shell-mac-arm64" -exec cp -a {} "$ARM64_BACKUP/chrome-headless-shell-mac-arm64" \;

# --- Step 3: Remove INSTALLATION_COMPLETE markers ---
# Playwright checks for this marker and silently skips if present — even when
# the needed platform variant (e.g. x64) is missing. Removing the markers
# forces the x86 install to re-download.
find "$PLAYWRIGHT_BROWSERS_PATH" -name "INSTALLATION_COMPLETE" -delete

# --- Step 4: Install x86 browsers for macOS 12/13 (Intel) ---
# Firefox and ffmpeg share the same subdirectory for both architectures, so
# this step overwrites the ARM64 copies with x64 — which is intentional since
# x64 binaries run on Apple Silicon via Rosetta 2.

# --- Step 5: Restore ARM64 Chromium files ---
# Copy arm64 subdirectories back into the browser revision directories so both
# architectures coexist (chrome-mac-arm64/ alongside chrome-mac-x64/).
