/* ============================================================
   Besocial — Case studies
   Design systém podle Besocial Deck TemplateV1
   ============================================================

   POZOR: tokeny se liší od současného produkčního style.css.
   Template V1 je novější identita:

     token           produkce (starý)   template V1 (nový)
     warm-base       #E8E4DD            #F4F1EB
     deep-ink        #1A1A1A            #1E1E1C
     signal-blue     #0033FF            #0047FF
     pulse-yellow    #FFC107            #FCB900
     font            DM Sans            Figtree
     radius          8/16/24/32         6/12/20/pill

   Proto jsou všechny tokeny scopované do .bs-v2 a nepřepisují
   zbytek webu. Case studies tak můžou běžet v nové identitě,
   i když homepage zůstane zatím na staré.

   Použití:
     <body class="bs-v2">              … pro stránky detailu
     <section class="bs-v2">           … pro sekci vloženou do index.html

   Fonty do <head>:
     <link href="https://fonts.googleapis.com/css2?family=Figtree:wght@300;400;500;700;800&family=Playfair+Display:ital,wght@1,500;1,700&display=swap" rel="stylesheet">
