 * ---- Shared polish pass ----

 *   1. No focus indicator anywhere. Keyboard and switch users had no way
 *      to see what was selected. :focus-visible (not :focus) so a mouse
 *      click doesn't leave a ring behind.
 *   2. Wide content (the rules stat tables, the battlefield) could force
 *      the whole page to scroll sideways on a phone. Now each wide block
 *      scrolls inside its own box and the body never does.
 *   3. Motion played unconditionally. Honour prefers-reduced-motion.
