/* Carvico Cars — the data portal.
   Deliberately NOT the app site's stylesheet. The marketing pages are dark,
   rounded and gradient-heavy because they are selling something. This is a
   reference tool: white, dense, hairline rules, tabular figures, and one accent
   colour used sparingly. If a border needs a radius or a panel needs a
   gradient, the layout is wrong. */
