/* ==========================================================================
   hra.css — shared look of the game pages (Úkoly, Hodnotitel profilů, Žebříčky)
   ==========================================================================
   Built after the PRO pages (pro. Služby / Nabídky) so the main site's game
   pages read like one product with them: page header with a gradient icon,
   two-column grid (content + 340px sidebar), goal card with a rainbow strip,
   section cards with their own headers, sidebar cards, filter buttons.

   Page-specific components stay inline on each page (.uk-*, .hp-*, .zb-*).
   The main site lacks some PRO colour tokens; they fall back here.
   Everything is scoped under .gx-page.
