    .SYNOPSIS  Normalise a severity to critical | warning | info | ok (v2.2.0).

    .DESCRIPTION

        The four canonical values match Add-DhAlertBanner -Severity and the

        alert / event-feed colours. For pasting in assessment output from other

        tools, three aliases are accepted (case-insensitive):

            high -> critical    medium -> warning    low -> info

        Anything else throws, naming the context.
