/* Legion of Data Nerds — "Marked Up" design.
   A printed data desk: a black-on-white newspaper nameplate, serif headlines (Newsreader), labels in a
   typewriter monospace (IBM Plex Mono), a lead story, a story river with a side rail. Signature marks:
   key sentences swiped with a yellow highlighter (<mark>), and red-pen notes in the margin for updates,
   corrections and how to read a chart (blockquote.note).
   Colour rules: black and white. Yellow = our key finding. Red = our notes, and costs / negative numbers.
   Nothing else: no brand blues, navies, greens or ambers, no rounded buttons. */
