/**
 * GradientText Component
 *
 * Animated shimmer text effect for premium users. Cycles through multiple
 * animation patterns over long intervals for a premium, varied feel.
 *
 * Patterns:
 * - sweep: highlight band oscillates left-to-right (ping-pong)
 * - wave: sinusoidal brightness wave moves across text
 * - pulse: entire text breathes between two intensity levels
 * - sparkle: random characters briefly brighten
 *
 * Inspired by Claude Code's terminal animations and Charm's Harmonica library.
 * References:

 *
 * @since v1.52.0
 * @updated v2.7.28 - Multi-pattern cycling animation system
