style(design): ajustare fina overlay-uri — acoperire completa text, opacitate 80%

- Overlay 1: top 2%→0%, height 17%→19% — acopera tot textul "La cireșe" de sus
- Overlay 3: width 30%→32%, top 2%→1% — textul "La scăldat" nu mai iese pe dreapta
- Overlay 6: height 46%→38% — nu mai acopera inutil partea de jos a hartii
- Opacitate confirmata 0.80 (80%) pe toate overlay-urile
