   Niche File Gateway - explorer stylesheet. One file, every colour a token so
   day and night share one layout. Day is the default (light palette on :root,
   so the page is light before any script runs); night is opt-in through
   html[data-theme="dark"], remembered per browser.

   The gateway blue #2f6fb7 is the same one the public link.php and index.php
   pages use, so the whole site reads as one thing.
