/* =====================================================================
   KUNSKAPSSTJÄRNAN – gemensam stil för menysidornas inställningar
   css/ks-menu.css   (används tillsammans med js/ks-menu.js)

   Byggd efter Emojiduellens meny (emojiduelmenu.php): numrerade paneler
   med valknappar som radiogrupper, vippbrytare, "Så här gör du",
   "Det här tränar du" och "Resultat". Se templatemenu.php, avsnitt 3.

   Struktur:
     <div class="km-meny ks-reglage">            mittkolumnen
       <section class="km-panel">
         <h2><span class="km-nr">1</span>Rubrik</h2>
         <span class="km-etikett">Underrubrik</span>
         <div class="km-rad" role="radiogroup" aria-label="…">
           <button type="button" class="km-val" role="radio" data-v="…">Text <small>Förklaring</small></button>
         </div>
         <p class="km-liten">Hjälptext</p>
         <div class="km-brytare">…<label class="km-vippa"><input type="checkbox"><span></span></label></div>
       </section>
       <section class="km-panel km-info"> <h2>Så här gör du</h2> <ol class="km-steg">…</ol> </section>
       <section class="km-panel km-info"> <h2>Det här tränar du</h2> <ul class="km-tranar">…</ul> </section>
       <section class="km-panel km-info"> <h2>Resultat</h2> <div class="km-stat">…</div> </section>
     </div>

   .ks-reglage gör att css/style.css låter knapparna behålla färgen i
   temana ljus och hav (annars blir alla knappar i main grå).
   Alla färger följer temat. Valt alternativ: gul ram och bock, samma gula som STARTA.
   På mobil läggs en extra STARTA-knapp sist i mittkolumnen (KSMeny.start).
