/* bis-compare.css - page styles for /midnight-season-2-bis-compare/.

   CHROME-NEUTRAL BY CONSTRUCTION, the tier-stats.css contract: every selector
   is `.bc-*` prefixed, there are ZERO token declarations, and there is no
   :root / body / bare-element rule anywhere in this file. The page is FRAMED
   (it shares header.php + footer.php + the theme engine with the rest of the
   site), so it must inherit the standard site look with no scoping fix - a
   single bare-element rule here would leak into the shared chrome.

   Every colour is a var() off the site's own theme tokens with a conservative
   fallback, so all themes and the per-viewer font picker follow for free. */
