-/**
- * v1.7.0 — Advanced settings sheet.
- * v1.7.2 — widened to `4xl` and re-laid into a responsive two-column
- * grid.
- * v1.8.6 — rebuilt as a single column. The two-column data|reminders
- * grid read as overloaded; the sheet now narrows to `2xl` (~672px) and
- * stacks bordered section cards in most-used-first order. One spacing
- * rule throughout — `space-y-4` between cards, `divide-y` + `py-3` rows
- * inside each card (the `<SettingsGroup>` card owns the dividers).
- *
- * v1.9.0 — the Data group split. It had carried both operator data
- * portability and the developer-facing external API in one frame; the
- * API endpoint now sits in its own `Externe API` group so the two
- * audiences no longer share a card. Order: Reminders → Lifecycle →
- * Data → Externe API → Danger.
- *
- *   - Reminders: notifications switch + reminder window (grace).
- *   - Lifecycle: pause/resume + end course + phases.
- *   - Data: intake Import + medications CSV Export (co-located).
- *   - Externe API: the per-medication ingest endpoint + token, with the
- *     request examples collapsed by default.
- *   - Danger zone: purge intake history + delete medication, set off by
- *     its own destructive-tinted card so an irreversible action never
- *     sits next to a routine toggle.
- *
- * Button styling is consistent: reversible / neutral actions are
- * `outline`, destructive actions are `destructive font-semibold`,
- * toggles are switches wrapped in labels.
- *
- * The Phasen button is sibling-swapped, not nested: `onRequestPhaseSheet`
- * closes this sheet first and lets the parent open the phase sheet so
- * the modal stack never exceeds two (D-3 §10 invariant 7). Each control
- * self-saves, so the footer slot stays empty.
