/* ════════════════════════════════════════════════════════════
   v10.6 — Full mobile audit fixes (Issue #17)
   ────────────────────────────────────────────────────────────
   New file. Include AFTER all other CSS in includes/header.php
   and admin/_partials/header.php.

       <link rel="stylesheet" href="<?= url('assets/css/v10.6-mobile-audit.css') ?>">

   Scope: every page (public, member, admin). Idempotent — only
   adds rules, does not override existing semantics.
