APP UI
The home screen leads with a single large HRV readout in tabular grotesque numerals — the number is the hierarchy. A tissue pink recovery index bar sits below it. Sleep, training load, and nutrition populate as compact data rows labeled in italic scientific notation. The background runs macro muscle fiber texture at the top edge, full-bleed, as both aesthetic and reminder of what the data refers to. The recovery detail screen surfaces a full-width HRV waveform in tissue pink across the upper half, with six specimen-style data tiles below: Cortisol Load, Sleep Efficiency, Muscle Readiness, Hydration Index, CNS Status, Recovery Score. Onboarding frames the profile setup as a lab form — fields for Sport, Phase, Baseline HRV, Target Recovery. One lab blue CTA at the bottom: Initialize Protocol.
