Binance market panel

dev.formless.binance-market is the reference for a rich Click frontend backed by an isolated external-data plugin.
The Host plugin uses public Binance REST for symbol search, klines, funding, and turnover, plus a long-lived WSS subscription for live bid/ask. Both paths use exact allowlisted external destinations through the generation-private egress bridge; Host does not terminate TLS or inspect payloads.
Two panels demonstrate the same capability:
- Binance Market Canvas: responsive HTML/CSS, shared Click theme tokens, market list, metrics, chart, and live book.
- Binance Market Pro: native daScript controls and plotting through the typed Host capability.
The WSS subscription is intentionally endless while demanded. It ends on explicit cancellation, panel/provider teardown, policy withdrawal, upstream terminal close, or generation disposal—not because of a short request timeout.
Use this architecture for services where discovery is request/response but live state is subscription-based. Keep external credentials and sockets in the Host plugin; send typed market results to panels.
