/**
 * SunLouvre Async File Upload UI
 *
 * Each <input type="file"> in a CF7 lead form is wrapped with .sl-asyncup.
 * The state machine is driven by the data-state attribute:
 *   idle      → pick UI visible, status hidden
 *   uploading → pick hidden, status visible with animated progress bar
 *   ready     → pick hidden, status visible with full green bar
 *   error     → pick hidden, status visible with red message
 *
 * @since 1.5.5
