/**
 * DirectTransfer Strategy
 * ------------------------
 * This is the simplest transfer mode — it directly sends data over
 * the WebRTC data channel (SimplePeer's `peer.send()`).
 *
 * Suitable for:
 *  - Text messages
 *  - Small files or JSON payloads
 *
 * Not suitable for:
 *  - Large files (>16MB) — for that, use a chunked/streaming strategy.
