Sylpheed port agent 975d24def2 port: --linger, so a scripted walk can observe what arrives after it settles ...

Last iteration I inferred the returned plate's fade from code-path identity
because the harness could not watch it: `--script` quits the moment the last step
settles, and the plate arrives on its declared ramp ~3.6 s later. A film of
`--script=cancel` stopped at 168 units and never reached 214.

`--linger=SECONDS` holds the run open past the walk. `_script_settled` still waits
for a hold before shooting -- a shot taken mid-fade is a photograph of a fade --
this only changes what happens after the shot, which was "exit".

Pre-registered: the returned plate sits at its floor until 214 units, then rises
to full by 236, the same ramp the boot shows. Measured:

  units=208.75  0.145404   floor
  units=216.58  0.158596
  units=224.41  0.179036
  units=232.25  0.203050
  units=240.08  0.215005   full -- boot path gives 0.2142 at t=236

So the return fades, identically to the boot, and it is now OBSERVED rather than
argued from the branch it takes.
