Subject: [PATCH] Ember playbook: the AMD watts source. The script samples the
 installed app's /api/state power_w for the AMD card every 10 s (a GET),
 counts the engine's own AMD watts, prints a fallback ladder (median per step,
 with the step's MH/s and MH/W) when the engine's AMD progress carries no
 watts, and names the source it used
