acme-proxy-admin 0.6.1

//! `/ui/expiring` — what lapses soon, and whether anything has replaced it.
//!
//! Read-only, like its API twin, and for that twin's reason rather than the
//! audit trail's: renewal is the client's own ACME flow, so there is nothing
//! here for a route to write. This file therefore contributes nothing to
//! `tests/admin_pages.rs::mutating_page_endpoints()`. See
//! [`crate::webadmin::handlers::expiring`].
