/* XWUIBarSiteFooter · reusable site-shell footer.
 *
 * Mirrors XWUIBarSiteHeader's contract for page-width / gutter:
 *   --xwui-bar-site-footer-max-width   inner content max-width
 *   --xwui-bar-site-footer-px          horizontal gutter
 *
 * Both are READ with a fallback where they are used, so they work however the
 * footer was mounted and wherever a host sets them: on the tag, on the
 * `.xwui-bar-site-footer` class, on a wrapper, or on :root. They used to be
 * defined only on the `xwui-bar-site-footer` tag below, so a footer built into
 * a plain host element had no gutter and no max width, and a rule on the class
 * could not change them. The tag block stays: a host that sets the variables on
 * the tag (the shell does) keeps working, and the tag still carries the defaults
 * for anything that reads them from outside.
