/**
 * v1.5.4 — Medication wizard end-to-end — one-shot cadence.
 *
 * Picking "Einmalig" on Step 5 collapses the path onto the 5-step
 * one-shot route ([1, 2, 3, 4, 8]). The wizard skips Steps 6 + 7
 * because the dose date already lives in Step 4 (course window).
 * Step 4's CourseWindowRow locks endsOn to startsOn for one-shot.
 *
 * The list-page "Nächste Einnahme:" chip is suppressed because the
 * design-synthesis lifecycle deactivates one-shot medications once
 * the single intake is logged. The spec only asserts the row name
 * appears on the list.
