/**
 * Story `play` helper for Monaco. Monaco lazy-loads from a CDN, then loads the language grammar,
 * tokenizes and lays out its scrollbars asynchronously. Wait until syntax colours are applied and
 * the rendered editor stops changing, so Chromatic never captures a half-painted editor.
 *
 * The overview ruler canvas is hidden: Monaco paints its 1px border non-deterministically between
 * page loads, which Chromatic reports as a diff on every build. Uses `performance.now()` because the
 * Storybook preview pins `Date`.
