/*
 * A utility-light stylesheet, hand-written (plan §7.4: no design system).
 *
 * The one place design carries weight is the coverage pill. Coverage is four-valued, and a
 * reader who takes `covered_subject_to_conditions` for `covered` has made the mistake the
 * whole system exists to prevent — so the conditional status is amber and visually distinct
 * from the green, never a lighter shade of it.
