/* ═══════════════════════════════════════════════════════════════════════════════
   ADAPTIVE DYNAMICS - Restraint-First UI
   ═══════════════════════════════════════════════════════════════════════════════

   Core Principles:
   1. No dashboards as default - direction, not scores
   2. Time > numbers - temporal and directional
   3. Silence is a first-class UI state

   This UI should feel closer to:
   - A navigation instrument
   - A weather system
   - A clinical observation window

   NOT a fitness tracker.
