/* Global responsiveness safety net:
 * - max-width: 100% on every replaced element prevents an oversized
 *   image / video / iframe from forcing horizontal scroll on phones.
 * - height: auto keeps the aspect ratio whenever an `<img>` has only
 *   width or only height attributes (or none) and we constrain it
 *   via CSS later.
 * Marketing site has its own reset (`site/css/reset.css`); this
 * mirrors that policy inside the dashboard SPA. */
