/* ---------- ambient mode (long-press) ----------
 * The glance hero: the countdown, the progress bar and the activity label
 * form ONE block, centred as a unit so the void above and below it match.
 * #app detaches to a fixed, full-viewport box: the block therefore centres
 * on the SCREEN, and body's safe-area padding (env()/--safe-area-inset-*)
 * can no longer skew the centre when the top and bottom insets differ.
 * .phase and .progress rejoin the flow as plain column items — .timer
 * stacks the digits over the bar, and .phase orders last, under the bar.
 * Cycle dots and controls stay out. The drift shifts the whole block a few
 * pixels every 45s to spare AMOLED panels from burn-in during all-night
 * dock duty. Steps, not glides — it must be imperceptible.
