   Qiangrun — shared site stylesheet
   Industrial reskin: warm graphite / raw-iron base (#1a1816 →
   #221f1c → #2b2723), molten-orange (#f26b1d) as the single FUNCTIONAL
   accent (active / CTA / brand), pill + circle geometry, compact bold
   type, heavy shadows for elevation on dark.

   Ported from the former warm-white index stylesheet; every "inverted"
   dark panel (topbar / inquiry / footer / captions) has been rebuilt
   for a dark base instead of being driven by var(--fg). Layout grids,
   spacing and breakpoints are unchanged so HTML positions stay put.

   Token contract: design-systems/spotify/tokens.css (:root verbatim).
