render.rs

//! The JSON renderings, shared by both front ends.
//!
//! One shape per admin resource, and **the boundary this module exists to
//! hold**: everything here is read by the CLI's `--json` branches *and* by
//! `src/webadmin/`, so a change is a change to a wire format two callers parse.
//! The human-readable renderings are the CLI's alone and live in
//! [`crate::cli::render`], which is where colour is woven in — none of it can
//! reach this file, so `--json` output stays byte-identical whatever the
//! terminal is.
//!
//! Each surfaces the admin-only fields the ACME wire format deliberately does
//! not carry (an order's revocation, an account's traceability columns), and
//! each **omits** rather than nulls an absent one, so a template asking
//! `{% if account.createdIp %}` is asking the question it looks like it is
//! asking.
