Feature: Viewport Screenshot as MCP Resource As an AI assistant I want to capture viewport screenshots as MCP resources So that I can provide visual feedback and quality assurance Background: Given the MCP server is running And the Blender addon is connected And a 3D viewport is active Scenario Outline: Capture viewport with different presets Given objects are visible in the viewport When I call viewport_screenshot with preset="<preset>" Then I receive a PNG image resource And the MIME type is "image/png" And the image shows the viewport in <display_mode> Examples: | preset | display_mode | | wire | wireframe | | matcap | matcap shading | | lit | solid/rendered | Scenario: Viewport screenshot for chat context Given a retopology work-in-progress When I call viewport_screenshot Then the PNG is suitable for LLM context And the image helps with visual QA And the screenshot is captured without full render overhead Scenario: Viewport screenshot with custom shading Given the viewport has specific shading setup When I call viewport_screenshot Then the screenshot respects current viewport shading And overlays are included/excluded based on settings Scenario: Viewport screenshot error handling Given no 3D viewport is visible When I call viewport_screenshot Then the call fails gracefully And the error message indicates no viewport found
