Description: A 3D animated one-page theme for Sift — Brain Games. Dark "premium night" palette lifted straight from the app, an animated WebGL-free 3D hero, tilting mode cards, a rotating language ring and Google Play / App Store download links. Bilingual: visitors in Arab countries are served Arabic (full RTL) automatically, everyone else English, with a manual EN/العربية switch. Built for siftpuzzle.online.
