/* AI Answer Readiness Score page (ar).
   Mobile first. Full width section backgrounds, content in a 1290px container,
   80px section padding from 860px up. Brand teal accents, no purple.
   Every text color is at least 4.5 to 1 on the surface it sits on; the gate
   tests/test-aars-page.php computes each pair.
   Interactive parts (tabs, calculator) are progressive: without the script every
   pillar panel is shown in full and the worked example stands in for the
   calculator. Motion only runs when the reader has not asked for less. */
