+# syntax=docker/dockerfile:1

+# Windows cross-build environment (x86_64), fully isolated from the Linux image
+# in Dockerfile so the two toolchains and standard libraries never interfere.
+#
+# Toolchain: llvm-mingw (clang + libc++ + the libc++ `std` module, MSVCRT
+# runtime) with the official SDL3 MinGW development package.
