/* public/css/components/margin-chat.css
 *
 * Ask Margin — the floating launcher, the slide-in chat panel, and the Command
 * palette that can hand a question to it.
 *
 * Moved out of layouts/today.css, where these rules lived because the markup
 * they style was built by the Today page. Nothing here was ever Today-specific:
 * the launcher and the panel are position:fixed and the stylesheet was already
 * loaded on every page, so the components appeared on Today only because that
 * was the one place the JS created them. They are mounted on document.body now
 * (public/js/components/marginChat.js), and their styles belong beside them.
 *
 * Unchanged from the originals apart from this header — the layout was already
 * correct for a global element.
