 - **LogRegistry & LogPruner:** Custom components for session metadata persistence and automated filesystem cleanup within the `logs/sessions/` taxonomy.
 - **psutil:** For system and process monitoring (CPU/Memory telemetry).
 - **uv:** An extremely fast Python package and project manager.
+- **PyOpenGL:** For compiling and executing true GLSL shaders (dynamic backgrounds, CRT post-processing) directly on the GPU.
+- **pywin32:** For custom OS window frame manipulation on Windows (e.g., minimizing, maximizing, closing, and dragging the borderless ImGui window).
 - **pytest:** For unit and integration testing, leveraging custom fixtures for live GUI verification.
 - **Taxonomy & Artifacts:** Enforces a clean root by organizing core implementation into a `src/` directory, and redirecting session logs and artifacts to configurable directories (defaulting to `logs/sessions/` and `scripts/generated/`). Temporary test data and test logs are siloed in `tests/artifacts/` and `tests/logs/`.
 - **ApiHookClient:** A dedicated IPC client for automated GUI interaction and state inspection.

 - **Synchronous IPC Approval Flow:** A specialized bridge mechanism that allows headless AI providers (like Gemini CLI) to synchronously request and receive human approval for tool calls via the GUI's REST API hooks.
 - **High-Fidelity Selectable Labels:** Implements a pattern for making read-only UI text selectable by wrapping `imgui.input_text` with `imgui.InputTextFlags_.read_only`. Includes a specialized `_render_selectable_label` helper that resets frame backgrounds, borders, and padding to mimic standard labels while enabling OS-level clipboard support (Ctrl+C).
 - **Hybrid Markdown Rendering:** Employs a custom `MarkdownRenderer` that orchestrates `imgui_markdown` for standard text and headers while intercepting code blocks to render them via cached `ImGuiColorTextEdit` instances. This ensures high-performance rich text rendering with robust syntax highlighting and stateful text selection.
-- **Faux-Shader Visual Effects:** Utilizes an optimized `ImDrawList`-based batching technique to simulate advanced visual effects such as soft shadows, acrylic glass overlays, and **CRT scanline overlays** without the overhead of heavy GPU-resident shaders or external OpenGL dependencies. Includes support for **dynamic status flickering** and **alert pulsing** integrated into the NERV theme.
+- **Hybrid Shader Pipeline:** Utilizes an optimized `ImDrawList`-based batching technique to simulate UI effects such as soft shadows and acrylic glass overlays without the overhead of heavy GPU-resident shaders. Supplemented by a true GPU shader pipeline using `PyOpenGL` and Framebuffer Objects (FBOs) for complex post-processing (CRT scanlines, bloom) and dynamic backgrounds.
 - **Interface-Driven Development (IDD):** Enforces a "Stub-and-Resolve" pattern where cross-module dependencies are resolved by generating signatures/contracts before implementation.
