Vibe Bro’s heads-up
Combining values from different frames without the correct transform can produce plausible-looking but physically incorrect results.

Supported: Frame and unit agreement is required before comparing coordinates; ROS REP 103 documents conventions rather than guaranteeing all systems share them.
