// The bindings file (vRIO's format, shared grammar):
//
//   key <name>      button <addr> [toggle]
//   key <name>      axis <axis> deflect <n> | rate <n>
//   pad <button>    button <addr> [toggle]
//   padaxis <src>   axis <axis> [invert] [deadzone <d>] [rate <n>]
//
// <addr> is a RIO input address: lamp buttons 0x00-0x47, internal
// keypad 0x50-0x5F, external keypad 0x60-0x6F. Loaded from
// bindings.txt beside the exe; written there (self-documenting, with
// the full default profile) on first run. Bad lines are logged and
// skipped, good lines always win.
