/**
 * Settings > Notifications is the one home for every reminder kind, each
 * card gated on its module and failing open.
 *
 * v1.18.0 — mood reminder on `mood`, low-stock on `medications`.
 * v1.44 — the Coach nudges came back (gated on the Coach surface), the
 * checkup reminder switches joined (not a module, always shown), and a card
 * names the reminders set where their subject lives (dose times on the
 * medication, the cycle reminders in the per-event matrix).
