   Webtures gorsel sistem (viz)
   Ilk kullanim: Agentic Web Optimization. Artik sayfadan bagimsiz:
   .viz sarmalayicisi olan her yerde calisir.
   --------------------------------------------------------------------------
   Tek gorsel dil, alti panel tipi: cizgi (chart), bar, halka (ring/donut),
   akis (flow), suzulen etiket (pills), sayac (ticker). Hepsi ayni kart
   kabugunu, ayni koyu paneli ve ayni tipografiyi paylasiyor.

   Hareketin kaynagi CSS. Animasyon dongusu yok: cizgiler stroke-dashoffset
   ile kendini ciziyor, barlar scaleX ile buyuyor, halkalar pathLength="1"
   hilesiyle yuzdeyi dogrudan dasharray'e yaziyor. Uc-dort keyframe butun
   sayfayi besliyor; her panel yalnizca gecikme ve sure ile farklilasiyor.
   JavaScript sadece sayac ve hover icin calisiyor.

   Kritik kural: metin SVG icinde DEGIL, uzerine konumlanan HTML katmaninda.
   SVG <text> hem dinamik degerlerde guvenilmez hem de tipografi kurallarinin
   disinda kaliyor.
