Supporting depth
Explainers
Mechanism-level deep-dives and terminology entries (sleep architecture, circadian biology, hormonal pathways, glossary terms like sleep latency or REM vs deep sleep) that exist to support the Life-Stage and Neurodivergent clusters, not to stand alone as general-audience content. Every explainer names the life-stage or neurodivergent guides it supports and is linked from them, forming the dense internal cross-link mesh the brand relies on for topical authority. Boundary: does not restate life-stage-specific guidance or safety advice; it explains the underlying biology those guides apply.
