/*!
 * Mammo theme - expert answer layer
 *
 * Loaded after mammo.css. Everything here is scoped to .mammo-* classes so it
 * never fights the inherited Donut/Bootstrap rules.
 *
 * Design notes
 * ------------
 * The page is a reference document, not a forum thread. Authority comes from
 * provenance, so the signature device is the "rail": a coloured vertical rule
 * running the full height of the answer, the way a countersigned document is
 * marked down its margin. Everything else stays quiet.
 *
 * Type: Literata for the question and the short answer (a reading face, so the
 * part people actually read looks like prose), Public Sans for UI and body.
 * Both are public-service typefaces, which suits a site whose job is to be
 * trusted rather than admired.
