   Clue identity layer.

   The offline demo started life as a generic Windows-utility mock, so its
   chrome was flat grey with a square-cornered send button. This block re-dresses
   the same DOM as the real Clue desktop client: a soft jade tray that holds two
   floating panels, a filled jade primary action, pill tabs and bubbles. Only
   surfaces, radii and colour change — every element keeps its behaviour, so the
   tour script and the accessible names stay untouched.
