/* Checks and switches, Arc-style (piece 9, 2026-10-29).
 *
 * Arc references: checkbox, radio-group, switch. Tokens: arc_tokens.css.
 *
 * - Native checkboxes and radios portal-wide keep working in their forms;
 *   appearance: none and the Arc control tokens draw them. The check draws
 *   in from the left once the fill lands; the radio dot springs in; the
 *   square or ring dips to .94 on press and springs back. :indeterminate
 *   (set from script) draws a dash. No JS.
 * - .oc-switch (or any checkbox with role="switch"): a track and a thumb
 *   that slides on the spring, for on/off settings.
 * - The portal's own switches (Settings .toggle, Mission Control .mc-switch,
 *   admin heartbeat .toggle .slider) take the same compact geometry and
 *   motion; their markup is unchanged.
 * - Out of reach: PM OS plates (D7), chart_kit menus, the chat pane and Helm
 *   dock (group F), the shell, and inputs another component hides and
 *   paints itself (a sibling track or slider, .helm-seg, .hd-code, .mc-sr).
