A breathing trainer you understand the instant it opens. Breathe in as the orb grows, hold as it stays, breathe out as it shrinks — sound (rising↑ / steady / falling↓) and vibration let you follow without watching. Three evidence-based patterns: Box (4-4-4-4, balance), 4-7-8 (calm & sleep), Coherent (5.5-5.5, peak HRV ~6/min). Breathing as form, not text. This interactive module represents Breathe with the orb inside the Atelier platform. Built using HTML5 and modern JavaScript for maximum performance and design fidelity.
