confium-wasm 0.5.5

//! Browser/Node.js **verifier** package for Confium.
//!
//! wasm-bindgen surface, `wasm32-unknown-unknown` target, verifier-only by
//! design. Browsers verify; servers sign.
//!
//! Each subsystem is gated by a `verify-*` Cargo feature so consumers can
//! tree-shake aggressively. All features are on by default for out-of-the-box
//! ergonomics.
