/**
 * @fileoverview Shared constants, utility functions, and SSE event type registry for all frontend modules.
 *
 * This is the first script loaded in index.html. Every other frontend module depends on the
 * globals defined here: timing constants, Z-index layers, respawn
 * preset definitions, the SSE_EVENTS registry, and shared utilities (escapeHtml,
 * getEventCoords, scheduleBackground, urlBase64ToUint8Array).
 *
 * @globals {function} urlBase64ToUint8Array - VAPID key conversion for Web Push
 * @globals {function} scheduleBackground - scheduler.postTask wrapper (background priority)
 * @globals {function} getEventCoords - Unified mouse/touch coordinate extractor
 * @globals {function} escapeHtml - XSS-safe HTML escaping
 * @globals {object} SSE_EVENTS - Centralized SSE event type constants (~73 event types)
 * @globals {Array} BUILTIN_RESPAWN_PRESETS - Built-in respawn configuration presets
 *
 * @dependency None (first in load order)
 * @loadorder 1 of 15 — constants.js → mobile-handlers.js → voice-input.js → notification-manager.js
