/* ============================================================
   cafe-core.css — sdílený engine pro Altán (kavárna & all-day bar)
   Vychází z Vítova liquid-glass enginu (shared.css + fv-core.css),
   přepsáno do TEPLÉ kávové palety. Dvě témata: tmavé espresso (default)
   a světlé „cream". Živé pozadí = jedna pevná vrstva (blury + dýchající
   tečky), liquid glass všude propouští rozmazané pozadí, reaktivní okraj
   závislý na vzdálenosti od kurzoru. Smooth ease-in-out všude. Žádné
   useklé hrany. Descendery (p,y,g,j) nikdy neoříznuté.
