   Arun Search — brand stylesheet
   https://search.arunkumar.works

   Loaded by Nginx (sub_filter injects a <link> before </head>) AFTER the
   stock simple-theme stylesheet, so same-specificity rules here win.

   NOTHING in the SearXNG image is modified. The simple theme exposes its
   whole palette as CSS custom properties on :root.theme-*, so the colour
   work below is just a variable re-map. Structural rules are kept minimal
   and additive so an image upgrade cannot break the site — worst case a
   rule stops applying and you get stock SearXNG.

   12. Layout & responsiveness

   out as 10rem margin + 45rem results + 5rem gap + 25rem sidebar + 2rem =
   87rem (1392px), but the breakpoint that switches to a single column is
   79.75em (1276px). Every viewport between 1276px and 1392px therefore
   overflows and shows a horizontal scrollbar. .page_with_header has the same
   flaw: a fixed `width: 85em` (1360px).

   Fixed below by making both containers centred and fluid, which also gives
   the header and the result column a shared alignment.
   -------------------------------------------------------------------------- */

/* Nothing may exceed the viewport.
