Sleep guides
Research-grounded posts about sound, scenes, and sleep. Plain-English translations of the studies — what the literature actually says, what's well-evidenced, and what's marketing.

Every voice phrase that works, what the Home Screen widget buttons do, and a walkthrough of building a bedtime automation in Shortcuts.
