/* ==========================================================================
   Elsiri app-site template
   --------------------------------------------------------------------------
   One stylesheet, meant to be reused for every app and game on elsiri.de.

   TO REUSE THIS FOR ANOTHER APP, YOU CHANGE TWO THINGS AND NOTHING ELSE:

     1. the --brand-* block directly below
     2. the files in img/  (icon.png, favicon.png, cover.jpg, shot-*.jpg)

   Everything past the brand block is layout and typography that has no opinion
   about which app it is dressing. Nothing here loads from a third party - no
   web fonts, no CDN, no analytics - because the privacy policy says so, and a
   policy that is not true is worse than no policy.
   ========================================================================== */
