/**
 * SOURCE OF TRUTH KEYWORDS: site-download-styles, mac-options, chip-icons, release-timeline,
 *   release-notes-style, download-modal, badge
 * WHAT:  Styling for the parts of the launch page that depend on the release: the Apple Silicon and
 *        Intel download options, the small chip badges, the Releases timeline, and the "download
 *        started" dialog.
 * WHY:   Kept apart from sections.css so that file stays one responsibility and so everything that
 *        is filled in by downloads.js is in one place. Values come from tokens.css; nothing here
 *        introduces a raw colour or size.
 * WHERE: Fifth stylesheet loaded by site/index.html, before responsive.css so its media queries win.
