UI components

A vertical delivery timeline: completed steps get ticks and times, the current step pulses, and an ETA heads the card.

A pull request checks panel: running, passed and failed jobs with durations, expandable failure logs, and re-run.

A flight card: route with a progress plane, gate and seat in large type, live delay or gate changes, and alerts.

The “agent is working” row above a chat composer: four animated indicators, a shimmering label and a live timer.
