Heavy vibe-coding warning, but it works for me!

Just set API_TOKEN env var to the value of cookie api_token from audioteka.com in you browser after logging in. The token is valid for ~20 minutes, after that, you need a new one.

Launch

Where the hell do I find complete docs for XML launch files?
- https://design.ros2.org/articles/roslaunch_xml.html seems to be the canonical doc
  - but XSD schemata are machine-readable, not human-readable
  - also, it is missing lots of stuff (launch_ros.actions), so e.g. push_ros_namespace is not mentioned in this doc
- https://docs.ros.org/en/rolling/How-To-Guides/Migrating-from-ROS1/Migrating-Launch-Files.html
  - this is a quite good source, but it isn't comprehensive
use_sim_time hell (i.e. no support for global parameters)
- https://discourse.ros.org/t/ros2-use-sim-time-leads-to-inconsistent-clocks/42030/2
