Run clang-format (the repo's .clang-format: LLVM base, 120 cols, tabs, Allman functions) over every source file so the tree is formatter-clean. Whitespace only -- no behavior change; full x64 + x86 suites pass. Also set SortIncludes: false in .clang-format. Windows include order is load-bearing (windows.h must precede tlhelp32.h / mmreg.h / xinput.h / dinput.h; winsock2.h must precede windows.h), and the default alphabetical sort reorders tlhelp32.h ahead of windows.h -- a build break. Leaving order alone keeps the manual, correct grouping.
