/* public/css/calc-tabs.css   — REVISED 2026-05-02 (round 3: tightened selectors)
 *
 * Tab styling for calculators with Quick + Advanced modes.
 * Plus embed mode styles (when ?embed=1).
 *
 * IMPORTANT: embed-mode selectors target SPECIFIC aicost-* and calc-* classes,
 * NOT generic <nav>/<header>/<footer>. Tool views legitimately use <nav class=
 * "calc-breadcrumbs"> and <header class="of-hero"> etc. for content — hiding
 * those would break the calculator.
