/* CIT Thinking Compass (/thinking/, /en/thinking/), pages generated by tools/pagegen/build_thinking.py.
 *
 * Calm, typographic, evidence-forward. Navy brand ink on a cool paper, one accent per pillar used the same
 * way in cards, the radar and the crosswalk chips: Think deep blue, Create warm coral, With AI teal. Light
 * accents pass WCAG AA (4.5:1) on #ffffff and on --bg-alt; dark accents pass on --bg in dark mode. Pillar
 * meaning is never colour alone: every chip carries its skill id (T/C/A) and name.
 * Every state is complete without JavaScript: details/summary carry the explorer and the FAQ, the tab
 * panels and the loop stages are all visible, the radar is server-rendered SVG with a text alternative. */

   outranks the menu's own text-* classes. Without this block the menu rendered as one run of blue words
   with no spacing and no pill (live, 2026-11-08). Same pattern as philosophy.css / exam-inquiry-ai.css:
