HUD header: keep ROUND on one line, compact phase badge (▲ PEAK ▲) + NEW GAME so the whole row fits in normal and peak

HUD: shrink Help button to '?'; nowrap button labels so Help + New Game stay on one line

Add How-to-Play button + tip; rename to 'Mumbai Local' (drop PANIC in brand board + splash title)

GPU tuning: @spaces.GPU duration 90->60, max_new_tokens 768->320, remove diagnostic logging

Fix ZeroGPU anonymous-quota fumble: set window.supports_zerogpu_headers so @gradio/client forwards the x-ip-token (PRO quota instead of anon 60s)

Warm VoxCPM2 at startup (under ZeroGPU emulation) + load_denoiser=False — fixes lazy-import CUDA-init error

Shim legacy generation output classes so the mamba-ssm hub kernel imports on transformers 5.x

Nemotron-3-Nano fast Mamba path: native NemotronH (transformers>=5.8) + hub kernels, drop mamba_ssm wheel (fixes NVML fork assert)

Load Nemotron on CPU, move to GPU inside @spaces.GPU (fixes NVML fork assert)

Disable Nemotron thinking (enable_thinking=False) so the dispatcher emits clean JSON

Part 2: @app .api game endpoints + @gradio/client frontend (ZeroGPU auth-forwarded GPU calls)

Expose demo=app for gradio reload mode (it launches the demo global)

app_file=frontend/server/app.py with SPACE_ID-gated module launch, ssr_mode=False

Switch to gr.Server (Gradio Server mode) — fixes the 7860 double-bind

Deploy Mumbai Local Panic — Nemotron(ZeroGPU) dispatcher + VoxCPM2 voice
