/* Ask Your Tutor — one stylesheet for the ask page and every answer page.
 *
 * [2026-09-27] The ground, glass and hero are the CBSE hub's system (/assets/shell/tokens.css
 * colours, Playfair headings, the orange primary), carried over from the 2026-08-31 redesign
 * (preview.php) so the ask page, its answer pages and /education/cbse-tutor/ read as one product.
 *
 * Class names are prefixed on purpose. The shell loads last and answers generic names itself —
 * `.hero`, `.card`, `.shape` all get repainted — so nothing here is called that.
