/* Kitt Online — the mobile variation of contents/css/common.css.
 *
 * THE SAME DESIGN SYSTEM, DRAWN FOR A THUMB. Every token below is copied
 * verbatim from the desktop file, and every component class that means the same
 * thing keeps the same name — .card, .btn, .badge, .field, .input, .alert,
 * .toolbar, .text-muted. That is the whole discipline: markup written for a
 * Kitt view reads the same here, and a person moving between the two apps is
 * looking at one product.
 *
 * WHAT IS DELIBERATELY DIFFERENT, and it is only the layout primitives:
 *
 *   .app-shell   a column (topbar / main / tabbar), not a grid with a sidebar
 *   .tabbar      the mobile variation of .sidebar — the same js/nav.js entries,
 *                drawn as four thumb-sized tabs at the bottom of the screen
 *   .sheet       the mobile variation of .drawer — it rises from the bottom
 *                edge instead of sliding in from the right
 *
 * Everything else a phone needs is a size, not a new idea: 44px minimum tap
 * targets, `env(safe-area-inset-*)` so the tab bar clears the home indicator,
 * and 16px inputs so iOS does not zoom the page when one is focused.
 *
 * NOT a copy of the desktop file with overrides. Two thirds of that file is
 * a sidebar, a workspace bar, data tables and charts, none of which exists
 * here — and a stylesheet carrying rules for markup that cannot occur is one
 * nobody can safely change.
