Update README.md

Add mandatory social (Posted on X) link to hero

Nemotron-forward ears (faster-whisper as fallback), site-wide centered section intros

Re-encode alpha webms (Chrome-friendly VP9 alpha, auto-alt-ref off, keyframes)

Fix contrast (dark text + deep accents), single-line hero title, YouTube above demo, centered intros, robust video autoplay

Fix sprite-sheet animation: pixel-based background-position steps

Redesign landing: high-contrast UI, sprite animation, alpha videos, emotion row, YouTube, field notes

Fix ZeroGPU build OOM: drop NeMo (unbuildable), keep VoxCPM voice on GPU + faster-whisper ears; don't pin torch (use preinstalled 2.8.0)

Wow UI: hero copy, voice/text labels, YouTube embed, What-can-it-do / Why-different sections

Full stack on ZeroGPU: VoxCPM voice + Nemotron ASR + MiniCPM brain (@spaces.GPU)
