 * Home page.

 * Follows the house landing-page style set by ai-for-education.css and
 * tutoring.css: the same blue/teal palette, 28px cards on soft blue shadows,
 * centred section titles, the gradient accent band, the gradient primary button
 * and the same 136/118/108 hero rhythm that clears the fixed navbar. Keep them
 * in step — where a value here differs from tutoring.css it should be because
 * the content differs, not by accident.
 *
 * Fonts come from the shared typography custom properties; never hard-code a
