- audio: default background music is now the santoor track (calm Persian),
rebuilt as a real plucked-santoor loop — fast metallic attack, shimmer
overtones, soft tonic drone, longer Dastgah-e-Shur phrase
- site: marketing logo is now the app's card-fan icon (Logo.tsx + icon.svg);
hero features the big logo with gold halo, floating suit motifs, and
polished section dividers
