The uptime bar, alive — labeled status-tracker rows that stack into an ops wall with a shared time axis. Boots with a sub-second left-to-right ignition cascade on first view, pulses the newest bucket, slides new buckets in on a live interval (suspended offscreen), and raises a hover chip with bucket detail. Statuses are shape-and-brightness coded, not just hue: dim operational, notched degraded, saturated glowing incident. Pure CSS animation, zero dependencies, visually-hidden textual summary per row, static wall under reduced motion.
