/* ============================================================
   First Look public pages: the www.zbang.ai system.
   Every page opens on night under a night bar, with its headline at
   poster size in Sofia Sans Extra Condensed; the content below sits on
   white and light grey. Buttons are pills (ink on light, white on night),
   everything else is square and flat. Blue marks text links and focus
   rings; light blue is night's accent. No cream, lime, salmon, gradients,
   shadows, serifs or italics. Loaded after app.css and brand.css on the
   logged-out pages only; the signed-in workspace keeps its own sheet.
