/* ========================================================================== 
   LEDKÁRNA / produktový detail
   Varianta produktu + nákupní panel

   Prefix vlastních tříd: lk-pd-

   Zásady:
   1. Soubor je oddělený od content-sections-lk.css.
   2. Nativní výběr variant Shoptetu se skryje až po úspěšném spuštění JS.
   3. JavaScript pouze doplní stabilní třídy lk-pd-* na existující prvky.
   4. Bez JavaScriptu zůstane původní výběr i nákup plně funkční.
