/**
 * BlossomWindSystem - Gentle wind gust management for cherry blossoms
 *
 * Unlike Autumn's more dramatic gusts, Blossom wind is:
 * - Less frequent (longer calm periods)
 * - Gentler (lower strength)
 * - Has ambient drift (constant subtle movement)
 * - Eases in/out smoothly for natural feel
