/// Advisory severity, derived from the advisory's CVSS score (`Unknown` when the
/// advisory carries no score).

/// Variants are declared in **ascending** order so the derived `Ord` makes
/// `Critical` the greatest. That gives us two things for free:
/// `iter().max()` over a set of severities yields the worst one (drives
/// `Summary::max_severity`), and a "severity descending" sort is a plain reverse.
///
/// Serializes as lowercase strings (`"critical"`, `"high"`, …) per the JSON
/// schema — independent of declaration order.
