NewAmp 1.8.0 turns Eviland from a reactive visualizer into a full generative visual engine, and adds a detached/pop-out visualizer window for a second monitor or projector. (Supersedes the never-tagged 1.7.4; its fixes are included.)

Added — Eviland becomes a generative visual engine

• Native MilkDrop-class waveform layer drawn into the feedback field before the warp (line / radial / spectrum-bar modes).
• Operator engine — every look is data (OperatorConfig): a base value plus per-channel audio-feature bindings, evaluated and clamped each frame. Serializable, interpolatable, shareable.
• Randomizer — endless musically-coherent looks across six archetypes (tunnel, kaleidoscope, liquid, lattice, nebula, strobe), each a short shareable seed (e.g. K7Q2-9XMF) that recalls the exact look on any machine.
• Director (auto-VJ) — reads song structure (sections, energy tiers, novelty) and crossfades looks on the beat, recalling a section's earlier look when it returns. Hands-free, fully overridable.
• Detached / undocked visualizer window — pop Eviland out via the Detach button in the fullscreen controls, pick a display, drag it to a second monitor/projector, and fullscreen it there while the main window stays browsable. Per-frame data streams over a low-latency message port; the feed auto-recovers if the main window reloads.
• Video recording — capture to WebM (VP9/Opus) at 60 fps via a parallel tap that never touches audible output.
• Live input — engine groundwork — typed capture core (voice DSP forced off); device-picker UI is a follow-up.
• @eviland/core — the engine staged as a zero-dependency, framework-agnostic library (build-isolated in-repo; standalone npm publish is a tracked follow-up; the build now fails on any drift vs src/visualizer/).

Fixed (post-review hardening)

• Visualizer no longer stutters under the Director — eliminated a per-frame JSON.parse(JSON.stringify) deep-clone of the whole operator config (the dominant GC source behind reported lag); steady-state frames reuse the owned config by reference.
• Library / History / Loved "load more" — page de-duplication is now race-safe (runs inside the state updater) and the library drops any page that resolves after the search changed, instead of appending stale/duplicate rows.
• Detached-window failures are visible and recoverable — a failed open, port hand-off, or renderer crash tears the window down, reports the reason in the controls, and releases the frame feed (no stuck "open" state).
• Recorder failures surface in the UI instead of silently no-opping the clip button.
• Atomic Eviland store updates; esbuild declared as a devDependency; @eviland/core drift gated in prebuild; detached smoke now requires a bidirectional port handshake.

Earlier (folded in from 1.7.4)

• Eviland "gold/cream smoke" root-caused and fixed (palette highlight, zoom focal point, section-flash); crisper field decay; album-art overlay opacity 0.72 → 0.55.
