/**
 * v1.4.16 Phase B7 — Settings → Export section.
 *
 * The consolidated Export page surfaces:
 *   - Measurements CSV
 *   - Medications CSV (with optional intake-history toggle)
 *   - Mood CSV
 *   - Full JSON Backup
 *
 * Each card must surface a title, a 1-line description, and a
 * download/generate button. SSR-only smoke test — interaction is
 * exercised by the e2e suite.
 *
 * v1.18.0 (S5) — the full health-record export moved out to its own
 * top-level "Gesundheitsakte" section; this page keeps only the generic
 * CSV/JSON data-out paths under a "Weitere Export-Optionen" / "Other
 * export options" sub-heading plus the import surface. Each component
 * owns its own contract test; this suite pins the page-level shape.
