/* Top Rank Insight — the reading view. Round 5 (29 Sep 2026): Archivo + IBM Plex Mono, flat and simple.
   A document you enjoy reading: plain panels, one accent, restrained headings (Ethan: "don't make it too big").
   Round 1-4 had clear-acrylic glass and an animated highlighter; both went for simplicity. Hexes from brand/palette.json. */
