Port the immersive GPU scenes: Plasma, Tunnel, Aurora, Ambient, Spectral Ribbon and Line Bed as QQuickRhiItems/ShaderEffects under a pulse-driven ShaderSceneLayer, plus the Qt-only Tunnel Flow (Tauri Canvas2D port) fed by the Viz16 stream. Scene rows live in the header view menu (no Off row); g cycles the ring. A fresh immersive open defaults to Split > Lyrics (owner ruling). OpenGL link fix (owner smoke: Tunnel black with "uniform _22 declared as type buf and type buf"): every ShaderEffect fragment with its own uniform layout now ships a paired vertex stage declaring the identical block — the shared spectrum.vert only ever linked under Vulkan. RHI hardening: render pass descriptors on the ping-pong targets (the Tunnel Flow segfault / Plasma dead window), mirrorVertically tied to the backend (!== OpenGL), ribbon sub-uploads carry setSourceSize. km
