   The one LIGHT surface on a dark page. Every other section is a
   dark card on a darker background, which is right for reading and
   wrong for typing: a dark input reads as disabled, and the caret
   is hard to find. Inverting the panel makes it unmistakably a
   place to enter something, and gives the page a visual full stop
   after the closing CTA.

   Colours are literal rather than token based on purpose. The
   palette in app.css defines ONE theme, a dark one; --text-primary
   is #e8ecf4 and would be invisible here. Reusing those names for
   an inverted surface would make the tokens mean two opposite
   things depending on where they are read. */
