/* ==========================================================================
   Block Builder — Structure (grid, layout, sizing, breakpoints)

   Stylování bloků vyrenderovaných serverem (BlockCompiler → PHP partials).
   Tento soubor řeší jen STRUKTURU — kolik sloupců, jaké paddingy, kdy zalom,
   geometrii tlačítek/obrázků/embedu. Veškeré barvy, pozadí, typografie nadpisů
   a brand prvky jsou v `blocks-theme.css` (editujte tam).

   Načítá se VŠUDE společně s blocks-theme.css: frontend layout, admin block
   builder canvas, TinyMCE iframe (přes @import v tiny.css).

   Mobile-first: na mobilu se sloupce stackují, typografie je menší,
   nad 768px se aktivuje reálný vícesloupcový layout.
