; DarkRoom — Windows installer
;
; Built by docker/windows/package.sh with makensis on Linux; see docs/dev/windows.md
; §5 for every decision below. Nothing here is Windows-specific to *write* —
; NSIS has always compiled on POSIX hosts.
;
;   makensis -DVERSION=0.12.0 -DSTAGE=/path/to/staging -DOUT=/path/to/setup.exe darkroom.nsi
;
; STAGE holds exactly what §5.2 installs: darkroom.exe, models\ and LICENSE.
; package.sh assembles it and applies the LFS-pointer guard before this runs.

; A 64-bit installer, not NSIS's default 32-bit stub. The application is
; x86_64 only, so nothing is lost; and it means the smoke test runs under a
; 64-bit-only Wine rather than needing an i386 multiarch: the 32-bit stub
; cannot load the WoW64 ntdll there and dies before showing a page.
