 * - Iridescent surface shimmer (rainbow that shifts with phase)
 * - Inner refraction layer (distorted interior highlight)
 * - Dynamic rim highlight (moves with light direction)
 * - Wobble deformation (non-circular oscillation)
 * - Trail particles (micro-bubbles following)
 * - Size-based visual characteristics
