Launching

LinUwUx must load into the Wine/Proton game process, not into Steam/Lutris/Heroic as a whole.

Pattern

Install (Install).
Set runner to GE-Proton or CachyOS Proton.
Put linuwux on the game launch path only.

By launcher

Steam — simplest; best tested
Lutris — command prefix or env on the game entry
Heroic
Faugus / umu

Wrapper vs raw LD_PRELOAD

Method	Notes
`~/.local/bin/linuwux %command%`	Preferred; appends to existing `LD_PRELOAD`
`LD_PRELOAD=…/liblinuwux.so`	Easy to clobber overlay/other preloads if you replace instead of append

Debug

LINUWUX_DEBUG=1 ~/.local/bin/linuwux %command%
