 * Additive layer on top of portal.css. Reuses :root variables from
 * portal.css. To roll back: delete this file and the mountShell()
 * <link> injection in common.js.
 *
 * Mobile-first: base styles target < 640px; @media queries widen up.
 * The prefers-reduced-motion override in portal.css already nukes
 * every transition for users who set that OS preference.
