# package-win.ps1 — Build the Windows NSIS installer.
#
# better-sqlite3 is a native module and its binary must match the runtime ABI:
#   - packaged app / `npm start`  → Electron ABI (v130 for Electron 33)
#   - `npm run start:backend`     → Node ABI
# This script swaps the prebuilt binary to Electron ABI before packaging and
# restores the Node ABI afterwards, so dev backend mode keeps working.
#
# No compiler needed: prebuild-install downloads prebuilt binaries (uses the
# npm prebuild cache when GitHub is unreachable).
#
# Usage: powershell -ExecutionPolicy Bypass -File scripts/package-win.ps1
