/*
 * build-win.cjs — build the Windows x64 installer. Works on Windows AND on macOS: electron-builder
 * fetches its own mac build of wine for the few Windows-only steps, so the laptop can produce the
 * exact installer the stage PC installs.
 *
 *   npm run build:win
 *
 * Two things this wrapper exists to guarantee:
 *
 *  - --x64. electron-builder otherwise targets the HOST architecture, so on an Apple Silicon Mac a
 *    plain `electron-builder --win` quietly produces an arm64 build that the stage PC cannot run.
 *  - a clean signing environment. There is no code-signing certificate. electron-builder aborts on
 *    an EMPTY WIN_CSC_LINK ("Env WIN_CSC_LINK is not correct"), so those variables are removed
 *    rather than blanked, and identity auto-discovery is turned off.
