//! Byte-round-trip conversions between upstream orchard and valar-orchard types.
//!
//! valar-orchard is a pure superset of upstream orchard 0.11 — same wire
//! formats, additive governance-visibility methods only. Conversions here
//! serialize through the public byte APIs and cannot fail for well-formed
//! inputs. Delete this module (and the `orchard_upstream` dep) when the
//! governance-visibility changes land in zcash/orchard upstream.
