/* =========================================================
   Tournament Site — Tutorial & Rules Stylesheet
   Loaded AFTER styles.css, home.css, and ban-status.css so it
   inherits the same header, bottom-nav, and color/type tokens.
   This file also carries the post-login popup styles used by
   tutorial-popup.js, since Home is the only other page that
   needs them (the popup only ever appears there).
