   alerts.css — Phase 4.

   Narrow, single-column form pages (create / manage / edit /
   expired). No new visual vocabulary: surfaces, borders,
   radii, buttons, and typography all reference tokens.css +
   components.css. This file only composes the layout.

/* Chrome / Safari autofill ignore standard background-color rules

 * --surface-raised, and -webkit-text-fill-color forces the input
