## Tonos Description
Tonos teaches the seven Hermetic principles: mind, correspondence, vibration, polarity, rhythm, causation, and generation, through produced one- to two-minute sessions. Each teaching pairs a narrated thesis with a frequency-anchored musical bed, scene-specific Canvas visuals, and a distinct haptic cadence. The result is a lesson that lands in the body as well as the mind.

Around the canon are five larger surfaces:

• The Invitation: a 60-second cinematic opening that introduces the framework on first launch and can be replayed at any time.

• The Seven Shadows: a darker companion teaching for each principle — the loud mind, the false pattern, the restless body, the split self, the stuck current, the haunted cause, the transactional exchange — paired so the Seven becomes a fuller spine.

• The Symphony: a ten-minute journey through all seven principles in sequence, culminating in a lit heptagon finale.

• The Codex: a written book mode that extends each teaching with longer-form prose.

• The Measurements: science cards citing peer-reviewed work on the Schumann resonance, heart coherence, vagal tone, neuroplasticity, and the body's own biophotons. Educational, not clinical.

Tonos runs on iPhone and iPad, offline-first. There is no account, no network activity at runtime, and no tracking. The app is designed for daily tuning, a single minute between the noise, and it treats the user as intelligent rather than fragile.
