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

// Tunnel Flow (immersive shader scene, mode 8 — Qt-only) — the
|
|
// QQuickRhiItem behind the feedback tunnel. Block B1 of the 2026-08-15
|
|
// immersive-completion contract (spec 02-tauri-tunnel-port.md): a rewrite of
|
|
// the legacy Tauri Canvas2D panel (TunnelFlowPanel.svelte) as
|
|
// qml/assets/shaders/tunnel_flow.frag. Same mechanism as PlasmaItem
|
|
// (cxx/plasma_item.h): a feedback ping-pong over two owned RGBA8 textures a
|
|
// ShaderEffect cannot own.
|
|
//
|
|
// QML properties are MEMBER-only (no NOTIFY): the QML wrapper
|
|
// (TunnelFlowScene.qml) computes the audio state (Viz16 smoothing, kick
|
|
// detector, the TAURI phase accumulator) and writes these on the pulse edge
|
|
// via pulseTick() — the same cadence contract as PlasmaItem/LineBedItem.
|
|
//
|
|
// Registered as QML type `TunnelFlowItem` in `com.blitzfc.qbz` 1.0 (see the
|
|
// .cpp).
