+REM Synthesise vulkan-1.lib from the system vulkan-1.dll.
+REM
+REM This removes the need to install the LunarG Vulkan SDK (~1 GB) just to get
+REM an import library: Windows already ships vulkan-1.dll, and we only need the
+REM matching .lib so the MSVC linker can resolve vkCreateInstance & friends.
+REM
+REM Run from a *plain* cmd/PowerShell: this script sets up the MSVC environment
+REM itself via vcvars64.bat.
+REM
+REM NOTE: deliberately avoids parenthesised if-blocks and avoids
+REM `setlocal EnableDelayedExpansion`, because this script's own paths contain
+REM "(x86)" -- expanding such a value inside a ( ) block truncates the block
+REM and yields "\Microsoft was unexpected at this time."
