/* ====== PERSONAS (Adversarial Review) ======
 * Design principles:
 *   - Harshness IS the visual (depth of color, glow intensity = data encoding)
 *   - Warm→hot color ramp: teal(1) → amber(2) → neil(3) → coral(4) → red(5)
 *   - Consistent overlay pattern (same as constellation/research)
 *   - Every pixel earns its place (Tufte)
 *   - Both themes must work
