 *
 * The splash and the announcement ticker were already handled where they are

 * Continuous movement is the specific thing that provokes nausea and dizziness
 * in vestibular disorders, so an unattended infinite animation is the worst
 * kind to leave uncovered.
 *
 * The scanner's cues are stopped rather than deleted: the dot keeps its red
 * glow and the beam stays parked over the QR, so the cashier can still see the
 * reader is live — the information survives, only the movement stops. Entrance
 * animations are collapsed to nothing, which lands the element exactly where it
