+Transport: one WebSocket per tab at `/ws`, JSON text frames `{ t: '<type>', ...payload }`. Client requests may carry `rid` (request id); the server's direct reply echoes `rid` (`ok` or `error`). Server pushes have no `rid`. Max frame 64 KB inbound (a compressed frame counts its inflated size); rate limit 40 msgs/s per connection (excess dropped with `error RATE`). Frames from 1 KB up are compressed with permessage-deflate (RFC 7692; `server/http/websocket.js WS_DEFLATE`: no server context takeover, a 2 KB server window, zlib memLevel 7 — about 72 KB of zlib state per connection); smaller frames go out plain, and a client that offers no compression, or caps the server window below 2 KB, gets plain frames. A measured solo session (rounds 3–5): 169 KB of server frames → 63 KB on the wire.
