A "Three ways to break it" chapter before Phase 1: the bare glass screen that
cracks when the mainboard flexes (do the Pico swap with the board out of the
case, on a padded surface, and tape the panel's edges with Kapton), the brass
screw posts that snap out of the shell when a screw is forced, and the charge
control that powering the core board's own USB-C bypasses (forum members
measured cells at 4.46 V and 4.74 V after powering the Pico's port). Steps 1
and 2 and the day-to-day section now follow it.
