Run a browser-local breathing pacer with custom inhale, hold, and exhale timing, live ring cues, phase charts, timeline history, and exports.

Estimate an HRV resonance breathing pace from resting profile inputs, then review cycle timing, trial windows, warnings, and comfort notes.

Plan a pranayama breathing sequence with timed ratios, prep, rests, cooldown, live rehearsal cues, phase balance, and validation warnings.
