/* ============================================================
   Charlie & César — styles

   A single-screen card: header, two-column stage, footer, sized to
   sit inside one viewport on a normal desktop or laptop without
   scrolling. Below ~900px it stacks and is allowed to scroll —
   crushing the type to avoid a scrollbar costs more than it saves.

   Committed dark palette with brass hairlines; the page does not
   follow the visitor's light/dark preference by design.
