Non-WebGPU browsers are now blocked by a non-dismissable onboarding modal with browser-specific instructions. WASM OOM errors null the unrecoverable Emscripten context and fall through to JS fallback. Futhark WebGPU assertion failures produce clearer error messages. - consentStorage: add webgpuAvailable field, shouldBlockDemos() - OnboardingModal: gated state disables close/escape/backdrop/finish - demo/+layout: second gate layer with inline block + spinner - ComputeDispatcher: OOM catch nulls futharkContext - futhark-webgpu: detect assertion/abort in context creation - 14 new tests (gate enforcement, OOM handling, assertion fallback)
