/*
 * 1:1 toy keyboard — ported from docs/design/simulator-v6-mockup.html (v6 定稿)
 * against the device's real top-view reference.
 * Device is laid out at a fixed 540px design width; .toy-scale gets a
 * JS-computed --scale so the machine fills the phone width losslessly.
 * Light states: a-idle | a-thinking | a-complete | a-needs_input | a-error
 * (idle is the visual default — unknown/grey is banned by spec §4).
