/* Lowpitch — Clarity v5
   One 12-column grid, and the grid is visible: hairlines in the dark sections sit on
   the real column edges, so the structure behind the page is on show.
   Palette: blue-black (#141b27) as ink, a deep "night" ink blue (#0c1119) for dark sections,
   brand plum (#281124) kept for the logo,
   brand orange (#eb682b) as the single spark, on a warm, slightly creamy paper. */
