mouse-mode.ps1

<#
================================================================================
  mouse-mode.ps1  -  Toggle Windows "Enhance pointer precision" (mouse accel).

  No argument  -> toggles:
       precision ON  (good on the desktop)  =  WORK
       precision OFF (raw aim in games)      =  GAMING
  Optional arg to force a mode:
       work | gaming   (also: bureau | jeu | on | off | 1 | 0)

  Shows the same red AMD-style overlay. Standalone: no svcl, no admin needed.
  Bind MouseMode.vbs to one Stream Deck key (it just toggles).
