# Direct path+version (not the workspace inheritance) so `default-features = false`
# is honoured: depending on wickra-data must NOT force wickra-core's `parallel`
# (rayon) feature on — the WASM binding needs a rayon-free build and the data
# layer never uses the parallel batch path. Native bindings re-enable `parallel`
# through their own wickra-core dependency (cargo unifies the features).

# OpenSSL) — the same backend tokio-tungstenite uses above — so it ships no
# bundled CA roots. (ureq 3.x hard-depends on `webpki-root-certs` regardless of
# TLS backend, which is CDLA-Permissive-2.0 and dead weight under native-tls.)

# Each exchange is gated so users only pay for the WS/REST stack they actually
# want. `live-binance` covers both the live WebSocket feed and the historical
# REST kline fetcher.

# `live-binance` with a statically built OpenSSL instead of the system one. The
# native-tls stack (tokio-tungstenite + ureq, unified on the same `native-tls`
# crate) links `openssl-sys`, which needs OpenSSL at build time. The manylinux
# and musllinux wheel containers do not provide it — manylinux lacks the headers
# and the musllinux build cross-compiles against a musl sysroot that has no
# OpenSSL at all — so the Linux wheels are built with this feature, which
# compiles OpenSSL from source and links it statically. No-op on macOS/Windows,
# where native-tls uses Security.framework / SChannel and never pulls openssl-sys.
