Reactor Core

Reactor Core is the containment vessel: a glowing core whose intensity maps to body battery, the time held in the core, three concentric containment rings filling with goal %, watch battery, and intensity minutes, hazard chevrons, and radial data pods. Settings let you recolor the accent, toggle wrist-raise seconds, and switch Clean, Standard, or Dense layouts — changes apply instantly, no restart needed. Features: - Signature look: the containment vessel - Shows steps, heart rate, Body Battery, stress, weather, and watch battery - Burn-in-safe AMOLED always-on layout - Live settings: accent color, seconds, density - Clean/Standard/Dense density modes
