   Colour: dark is the default theme; light applies via [data-theme="light"]

   Terminal-style panels keep the dark palette in either theme. Neutrals are
   warm (olive-tinted) rather than green-grey; green is the signal colour and
   amber (--finding) is reserved for real results and evidence.
   Every text token passes WCAG AA (4.5:1) on bg/surface/surface-2 in its
