//! Rich rendering for `bl show`.
//!
//! Lays out a header line (priority + status + id + title + claimed
//! badge), a compact metadata row (type, relative timestamps, tags),
//! a relations block (deps with inline statuses, gates, parent,
//! children, delivered/branch/remote meta), a wrapped description,
//! and an oldest-first notes log. Relative timestamps use a `now`
//! passed in so the whole module is pure and testable.
