/* ==========================================================================
   callouts.css: one look for every notice in the app.
   Tone (info / success / warning / danger / neutral) sets a soft background,
   a border, an icon tile and readable ink. Titles 14/600, body 13.5/1.55.
   Applies to the existing notice classes, so no behaviour changes.
