/**
 * Customer Pickup Display (0.10.0, ADR-053).
 *
 * Designed to be read from several metres away: order numbers use a
 * fluid clamp() so a 1920×1080 TV gets huge digits while a 320px phone
 * still fits. Status is never colour-only — every column and card
 * carries a text heading and an icon glyph. No flashing: a newly ready
 * number gets ONE short, reduced-motion-aware highlight, then rests.
