/* ============================================================================
   RetailRadar — shared design system for the static retailradar.hu site.

   Structure and typographic treatment follow precisionsteel.org (the reference
   the design was briefed against): a thin utility bar over a sticky header, a
   full-bleed hero with an eyebrow → oversized uppercase headline → paired pill
   CTAs, a chevron capability strip, then alternating content sections.

   The palette is deliberately NOT theirs. precisionsteel is a light site with a
   crimson accent; RetailRadar keeps its dark navy base and cyan/green radar
   accents, because the radar hero is the brand and a light treatment would
   erase it. Likewise the headline font stays Space Grotesk — the industrial
   feel here comes from the *treatment* (800 weight, uppercase, wide tracking),
   not from adopting their Chakra Petch.
