/* ===================================================================
   LinaAdvisor Landing — "Lina Transcript" style
   ===================================================================
   Restyle of the previous dark landing (slate #0f172a canvas with a
   cyan→violet gradient) into the Transcript design language: white
   canvas, near-black ink as the primary, and the LINA orange as a
   scarce accent. Every class name and DOM hook is unchanged — this is
   a skin, not a rewrite.

   Unlike the old file, colours live in custom properties so future
   changes propagate instead of being hunted down in 90 places. */
