/*
 * KLUBHAUS ALERT v5.1 — E32R35T Edition
 *
 * Target: LCDWiki E32R35T (ESP32-WROOM-32E + 3.5" ST7796S + XPT2046)
 *
 * Hold-and-release interaction model:
 *   - Hold finger → progress bar fills
 *   - Bar full → jitter/flash ("RELEASE!")
 *   - Lift finger → action fires (finger already off screen)
