iChris4andClaude Opus 5.5 771a143254 Flick the bare hands for a trick 
- A bare hand already feeds no Wii Remote motion (camera-tracked poses are too noisy to
  differentiate twice). In a cockpit race, both hands on the wheel rising together or a free bare
  hand rising fast now plays one shake on the remote's accelerometer: 150 ms, so the guest sees it
  on at least three frames, one cycle up to +2 g and down to the -3.6 g limit, as Dolphin's
  emulated shake does. A turn (one hand up, the other down) never flicks, nor does a lone hand on
  the wheel; a rise must last three samples and cover 5 cm within 150 ms, tracking jumps reset it,
  and flicks are 0.5 s apart. Wii Remote presentation only.
- debug.wiicompiled.inject <n>:flick plays the same shake, with the controllers or unattended, to
  tune it apart from the gesture. Docs: OPENXR.md, docs/quest-port.md.
