/* ============================================================
   THE ATTENTION ADVANTAGE — /attention-advantage/
   ------------------------------------------------------------
   Layered on css/style.css + css/tools.css + css/paths.css, the
   same way css/leaders.css is. Everything here paints from the
   semantic tokens, so the page follows the light/dark switcher;
   the print block at the bottom is the one place with literal
   colours, and it is excluded from the theme check by design
   (scripts/check-theme.mjs drops print rules) because a printed
   page has one theme and it is not the screen's.
