/* Motion Explorer component.
 *
 * Every rule is scoped to .motion-explorer and every class, id and custom
 * property is prefixed with "me-", so the component can sit inside another
 * site without clashing with its styles. The host page defines the --me-*
 * tokens (see the :root block in index.html for the complete list). Leave the
 * --me-f-* font tokens undefined to inherit the host page's fonts.
 *
 * Layout: a dark "monitor" (stage + transport bar) beside an instrument panel;
 * stacks into one column when the component is narrow.
