/**
 * Portable, type-preserving codec for relation-cache values (ADR-011).
 *
 * Every cached 1:1 relation snapshot is run through `@nhtio/encoder` before it is
 * handed to the cache service, and decoded again on read. The encoder round-trips
 * the rich types Lucid columns produce post-`consume` (Luxon `DateTime`, `bigint`,
 * `Date`, `Map`/`Set`, typed arrays, …), so cache-value fidelity no longer depends
 * on the host's BentoCache serializer preserving those types — the cache only ever
 * sees an opaque encoded string.
