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.

// Host-side setup for the opt-in Vulkan capture layer (coop_vk_layer). Registering it as a
|
|
// per-user implicit Vulkan layer makes the Vulkan loader insert it at vkCreateInstance -- so it's
|
|
// in the chain before a game (that caches its present pointer at init) can resolve
|
|
// vkQueuePresentKHR, the reliable early-presence path the inject-after-launch hook can't get.
|
|
//
|
|
// An implicit layer loads into *every* Vulkan app, so the layer itself only captures the process
|
|
// whose image basename matches the scoping file this writes -- keeping it inert for everything but
|
|
// the host's target. Registration is HKCU-only (no admin) and fully reversible.
