/* Kendini Keşfet — ortak tasarım dili, sürüm 2 (04.11.2026)
   Her oyun <body class="tema-…"> ile kendi renk dünyasını alır. Tema sınıfı olmayan sayfa eski görünümde kalır.
   Tema sözleşmesi (bir oyun sayfası yalnız bunları değiştirerek kabuğu boyar):
     --t-ana        birincil renk (düğme, ilerleme, bağlantı vurgusu)
     --t-ana-koyu   birincilin koyusu (hover, beyaz zemin üstünde metin)
     --t-ana-acik   birincilin çok açığı (chip, etiket zemini)
     --t-vurgu      ikinci renk (başlıktaki vurgu kelimesi, küçük süsler)
     --t-zemin      sayfa zemini
     --t-murekkep   başlık rengi
     --t-hero       giriş sahnesinin zemini (gradyan olabilir)
     --t-hero-metin giriş sahnesindeki metin rengi
     --t-cta        randevu çağrısı kutusunun zemini
   Giriş sahnesi: <section class="k-hero k-hero--sahne"> … <div class="k-hero-art" aria-hidden="true"><svg>…</svg></div></section>
   Oyun alanı ekrandayken body'ye .k-on-stage eklenirse alttaki sabit randevu düğmesi gizlenir. */
