//! HTTP admin API for the system-wide credentials store (`/v1/credentials`).
//!
//! Credentials are typed, encrypted secrets referenced by id. The list and get
//! endpoints return [`CredentialSummary`] (no plaintext, just a masked
//! preview); plaintext only flows internally to subsystems via
//! [`PgCredentialStore::fetch`] keyed by a stable id.
