 * "Thinking of you 💜" — a one-tap affectionate nudge from the partner sheet.
 *
 * Partner-initiated (like the gentle reminder), so it is guarded by a rate limit + quiet hours rather
 * than a per-type opt-out:
 *  - Per-user rolling 24h cap (transaction on `rate_limits/{uid}_thinking_of_you`) so it can't be looped.
 *  - Quiet hours: during the recipient's window the FCM push is suppressed, but the in-app record is
 *    still written so the love is waiting when they wake. (Improvement over the gentle reminder.)
 *
 * Writes a partner-safe `notification_queue` entry (in-app + the "Together" feed) and an FCM push.
