/**
 * @oxpulse/chat-widget — Emoji picker (#127).
 *
 * Searchable, categorized emoji picker. Zero-third-party-dep — bundles a
 * curated emoji dataset (~180 emojis, 8 categories) in emoji-data.ts.
 *
 * Lifecycle:
 *   show(anchorEl)  — appends picker to container, positions below anchor
 *   hide()          — removes from DOM, restores focus
 *
 * A11y:
 *   role="dialog", search input focused on open, Arrow keys navigate,
 *   Escape hides + restores focus, Tab focus trap.
 *
 * Used from:
 *   - Composer: emoji button in the toolbar → inserts at cursor position
 *   - ReactionQuickBar: "more" button → opens full picker for any-emoji reaction
