 * calculator-mobile.css — Mobile-only rules for the Rechner.
 *
 * RULES:
 * 1. Every rule MUST be inside one of these two blocks:
 *      @media (max-width: 767px)                         -> Phones
 *      @media (min-width: 768px) and (max-width: 1023px) -> iPad portrait
 * 2. NEVER add rules that apply at >= 1024px. Desktop is governed by calculator.css.
 * 3. Cap !important usage at 5 occurrences in this file. Justify each with a comment.
 *
 * Loaded AFTER calculator.css so cascade order favors mobile.
