   DESIGN INTENT — "deep water". Read before changing anything.

   • The ground is not flat black. It is layered light: two wide radial washes
     (teal near, blue far) over a deep ink base, so the page has depth the way
     water does. If someone flattens this to a single background colour the
     whole direction collapses.
   • The accent runs aqua -> blue as a gradient, used on ONE phrase per view.
     Spend it there and nowhere else; it stops reading as luminous the moment
     it decorates.
   • Surfaces are glass: a faint white overlay, a 1px light border, and blur.
     They should feel lit from behind rather than drawn on top.
   • Rounded corners are correct HERE (unlike the drawing direction) because
     the language is optical, not draughting.
   • Data is the ornament. Timestamps, durations and counts carry the argument,
     so they are set large and tabular rather than decorated.
