rem Downloads the prebuilt WebUI static library and header for Windows.

rem We link WebUI statically, so this fetches webui-2-static.lib rather than the
rem DLL the other bindings use. The header comes from the same archive on
rem purpose: a static link welds the two together, and a webui.h that disagrees
rem with the .lib produces a corrupt build rather than an honest error.

rem   set WEBUI_VERSION=2.5.0-beta.3 && bootstrap.bat  (pin a tagged release)
rem
rem Re-running this after a nightly moves will relink the NIF on the next
rem `mix compile` -- the Makefiles depend on the static library, not just on
rem the C source.
rem
rem Linux and macOS use bootstrap.sh.
