   panou dreptunghiular): FARA card/chenar - un gradient radial alb care
   se estompeaza complet spre transparent (nu spre o culoare opaca), deci
   bleumarinul hero-ului de dedesubt se vede exact neschimbat la margini -
   nicio muchie vizibila, haloul se confunda cu fundalul. Sigla completa
   (inclusiv subtitlul "Te Reprezinta") sta integral in zona luminoasa -
   raza de "platou" alb calculata explicit sa acopere colțul cel mai
   indepartat al siglei (jumatate-latime/jumatate-inaltime), nu procentual
   relativ la cutie (bug-ul initial: raza platoului era mai mica decat
   distanta reala pana la colțul siglei, lasand subtitlul in zona
   intunecata). Raza explicita `circle <px>` (nu procentuala) - precizie
   independenta de dimensiunea cutiei. Cutia insasi e mereu >= 2x raza
   totala de estompare, ca gradientul sa nu fie taiat de marginea cutiei
