// electron-builder afterPack hook — mac only.
//
// WHY (owner ruling 2026-10-13): mac.icon is the Icon Composer document
// (build/icon.icon); actool compiles it into Assets.car (the macOS 26
// Liquid Glass render) PLUS a backwards-compat icns — but actool's
// fallback icns caps at 256px (known actool behavior), which looks soft
// at Finder/Launchpad sizes on pre-Tahoe macOS. This hook swaps in the
// hand-packed full-res build/icon.icns (all 10 entries, 16→1024, packed
// via iconutil from the design's PNG exports) AFTER packaging and BEFORE
// signing, so:
//
//   macOS 26+  → Assets.car (CFBundleIconName) — true layered glass icon;
//   older mac  → icon.icns (CFBundleIconFile) — today's full-res flatten.
//
// Windows/Linux builds return immediately (their icons are static files:
// build/icon.ico / build/icon.png).
