   STEGU SNIPPETS — Design System CSS Library
   Verze: 1.0 | Duben 2026
   Autor: DECORSTONE s.r.o.

   POUŽITÍ:
   1. Vložit jednou do Shoptetu (Administrace → Vzhled → Vlastní CSS)
      NEBO
   2. Embedovat <style> blok přímo do každého HTML snippetu

   PRAVIDLA:
   - Vše v .stegu-block kontejneru — izolace od Shoptet CSS
   - Používej pouze třídy s prefixem stegu-
   - Nikdy neměň :root tokeny — jsou sdílené s custom.css
