Messenger features

• English and Arabic UI, an instant language switch, RTL layout, localized timestamps, and automatic direction for mixed-language messages and drafts.
• A mobile composer that follows visualViewport.height and offsetTop when the keyboard opens or pans the page. Safe-area padding, dynamic viewport fallback, 16px inputs, and support for browser pinch zoom are retained.
• Connection status from browser online/offline events. New messages queue in memory while offline and resume once on reconnection.
• Sample online/away contact presence, animated typing, and sending/sent/delivered/read receipts. These people-chat states and replies are disclosed as simulations in Settings and conversation information.
• Multiline composition (Enter sends, Shift + Enter adds a line), IME-safe Enter handling, bilingual emoji search, quoted replies, emoji reactions, and a jump-to-latest control.
• Image attachments under 5 MB (JPG, PNG, WebP, GIF), a removable draft thumbnail, a separate image viewer, 100–300% zoom, and download.
• Custom polls with 2–5 distinct options and one changeable local vote. Polls, presence, and media previews are separate reusable components.
• Animated assistant typing and streamed text, Stop, partial-response retention, retryable errors, copy, and natural clarification questions. Reduced-motion preferences are respected.

Messages, attachments, poll votes, product choices, and new contacts are saved in this browser using IndexedDB. Storage failures are shown in Settings, with a session-only fallback. Restoration keeps the most recent 500 messages per conversation. People chats do not deliver anything to another person. No calling, accounts or multi-user delivery service is implemented. Assistant transcripts also have a server-side SQLite demo archive, described below. The included contact names and portraits are sample data.
