/* ========================================
   STRANGE FRONTIERS POPUP
   ========================================
   One stylesheet for the popup, wherever it opens: the backdrop over the
   page, the panel that holds the content, and the round X on the panel's
   top right corner.

     strange-frontiers-character-creator  src/app/popup.css (this file)
                                          src/app/components/popup.tsx
     portfolio_site                       css/sf-popup.css (a copy)
                                          php/rpg/components/popup.php

   Both copies must stay identical: change it in the creator, then copy it
   to the site. The components in both repos draw the same markup and take
   the same options (see popup.tsx):

     tone   light (the site's white panel, a dark X) or dark (the creator's
            panel gray, a light X)
     size   narrow (480px), the default (720px) or wide (1100px)
     card   a card on its own: the card is the popup's edge, with no panel
            around it, and a smaller light X on its corner

   The X is the round button (css/sf-buttons.css). What's inside is its
   own component's. */
