+# Implementation Plan: Frosted Glass Background Effect
+
+## Phase 1: Shader Development & Integration
+- [ ] Task: Audit `src/shader_manager.py` to identify existing background/post-process integration points.
+- [ ] Task: Write Tests: Verify `ShaderManager` can compile and bind a multi-pass blur shader.
+- [ ] Task: Implement: Add `FrostedGlassShader` (GLSL) to `src/shader_manager.py`.
+- [ ] Task: Implement: Integrate the blur shader into the `ShaderManager` lifecycle.
+- [ ] Task: Conductor - User Manual Verification 'Phase 1: Shader Development & Integration' (Protocol in workflow.md)
+
+## Phase 2: Framebuffer Capture Pipeline
+- [ ] Task: Write Tests: Verify the FBO capture mechanism correctly samples the back buffer and stores it in a texture.
+- [ ] Task: Implement: Update `src/shader_manager.py` or `src/gui_2.py` to handle "pre-rendering" of the background into a texture for blurring.
+- [ ] Task: Implement: Ensure the blurred texture is updated every frame or on window move events.
+- [ ] Task: Conductor - User Manual Verification 'Phase 2: Framebuffer Capture Pipeline' (Protocol in workflow.md)
+
+## Phase 3: GUI Integration & Rendering
+- [ ] Task: Write Tests: Verify that a mocked ImGui window successfully calls the frosted glass rendering logic.
+- [ ] Task: Implement: Create a `_render_frosted_background(self, pos, size)` helper in `src/gui_2.py`.
+- [ ] Task: Implement: Update panel rendering loops (e.g. `_gui_func`) to inject the frosted background before calling `imgui.begin()` for major panels.
+- [ ] Task: Conductor - User Manual Verification 'Phase 3: GUI Integration & Rendering' (Protocol in workflow.md)
+
+## Phase 4: UI Controls & Configuration
+- [ ] Task: Write Tests: Verify that modifying blur uniforms via the Live Editor updates the shader state.
+- [ ] Task: Implement: Add "Frosted Glass" sliders (Blur, Tint, Opacity) to the **Shader Editor** in `src/gui_2.py`.
+- [ ] Task: Implement: Update `src/theme.py` to parse and store frosted glass settings from `config.toml`.

+# Specification: Frosted Glass Background Effect
+
+## Overview
+Implement a high-fidelity "frosted glass" (acrylic) background effect for all GUI panels and popups within the Manual Slop interface. This effect will use a GPU-resident shader to blur the content behind active windows, improving readability and visual depth while preventing background text from clashing with foreground UI elements.
+
+## Functional Requirements
+- **GPU-Accelerated Blur:**
+  - Implement a GLSL fragment shader (e.g., Gaussian or Kawase blur) within the existing `ShaderManager` pipeline.
+  - The shader must sample the current frame buffer background and render a blurred version behind the active window's background.
+- **Global Integration:**
+  - The effect must automatically apply to all standard ImGui panels and popups.
+  - Integrate with `imgui.begin()` and `imgui.begin_popup()` (or via a reusable wrapper helper).
+- **Real-Time Tuning:**
+  - Add controls to the **Live Shader Editor** to adjust the following parameters:
+    - **Blur Radius:** Control the intensity of the Gaussian blur.
+    - **Tint Intensity:** Control the strength of the "frost" overlay color.
+    - **Base Opacity:** Control the overall transparency of the frosted layer.
+- **Persistence:**
+  - Save frosted glass parameters to `config.toml` under the `theme` or `shader` section.
+
+## Technical Implementation
+- **Shader Pipeline:** Use `PyOpenGL` to manage a dedicated background texture/FBO for sampling.
+- **Coordinate Mapping:** Ensure the blur shader correctly maps screen coordinates to the region behind the current ImGui window.
+- **State Integration:** Store tuning parameters in `App.shader_uniforms` and ensure they are updated every frame.
+
+## Acceptance Criteria
+- [ ] Panels and popups have a distinct, blurred background that clearly separates them from the content behind them.
+- [ ] Changing the "Blur Radius" slider in the Shader Editor immediately updates the visual frostiness.
+- [ ] The effect remains stable during window dragging and resizing.
+- [ ] No significant performance degradation (maintaining target FPS).
+
+## Out of Scope
+- Implementing different blur types (e.g., motion blur, radial blur).
+- Per-panel unique blur settings (initially global only).
