"""FALLBACK only: a single car widget with its layout INLINED in the import (no %klayout).

    KW_TOKEN=... ./make_fallback_widget.py      # writes build/Car.prf.xml (0600: holds the token)

Use it if the remote-controlled shell (make_kw.py) renders blank on your phone, i.e. if your
Tasker's Widget v2 does not accept its whole layout / name from a variable. This shape rendered
on the target phone before the remote shell existed. Profile "Car hourly" -> task "Car Widget":
  1. HTTP Request GET car-<token>.txt  ("54 Disconnected 1791119700")
  2. JavaScriptlet -> %cver (read_at-now, cache-buster) %cago %cagecol
  3. Widget v2 "car": car-<token>.png?v=%cver + an age line; tap = refresh
The cost: every later change to the look means re-importing this file on the phone.
Actions are cloned from templates/actions.xml, the Time context from make_kw.TIME_CTX.
