When you open a reservation on a phone, the workflow bar now starts compact: you see the current status and the one required next step, with a control to expand the full tracker, inventory callout, and other suggested actions. Expanded details scroll with the rest of the reservation so you can read everything without losing context. Your expand/collapse choice is remembered for next time.
Step labels on small screens use short names (for example Pend. and Conf.) so they no longer overlap; screen readers still announce the full step names.
Desktop is unchanged—the full workflow stays pinned above the reservation details.
