Add Matrix Generation mode and expand documentation#81
Conversation
- README completely rewritten: both Slide Generation and Matrix Generation are top-level peer sections with equal depth. New tagline reflects the dual-mode tool. Matrix section documents input modes (theme/description), grid sizing, style modes, streaming, image generation, revalidation, all three views (grid/poster/reveal), and the full settings schema. - docs/user-guide.md restructured: Matrix Generation is now a full top-level section alongside the carousel pipeline (not appended after Tips). Expanded with views, revalidation, settings temperatures, and concurrency controls. - ModeSelector.tsx: replaced Instagram-specific slide card description with a broader slogan that covers the six-stage pipeline. https://claude.ai/code/session_0188EvRkkj6RFujggzp2bean
Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly expands Lucid's capabilities by introducing a new, independent 'Matrix Generation' mode. This mode enables users to create dynamic, AI-generated concept grids with various input and style options, real-time streaming, and robust revalidation features. Concurrently, the project's documentation has been thoroughly updated and reorganized to clearly present both the original carousel pipeline and the new matrix functionality, providing a more comprehensive and user-friendly guide to the application's expanded features.

Code Review
This pull request introduces a major new feature, the Matrix Generation mode, and significantly expands and restructures the documentation to cover both it and the existing Slide Generation pipeline. The changes in README.md and docs/user-guide.md are comprehensive and well-organized, providing clear explanations of the new functionality, including input modes, streaming generation, image generation, and revalidation workflows. The API reference has also been greatly improved with a clear tabular format.
My review found one minor point of clarification needed in the user guide regarding the process of saving a customized project configuration as a new template. Otherwise, the documentation updates are excellent and provide a great overview of the new features.

This section on customizing templates is a bit unclear. Step 3 says 'Future projects can be created from templates that reflect your refined defaults', but it doesn't explain how a user saves the current project's settings as a new template.
The README.md states that 'Any project configuration can be saved as a reusable Template', which implies a direct action is available in the UI. However, the user guide doesn't describe this action.
Could you clarify the workflow here? For example, if there's a 'Save as Template' button, it would be helpful to mention it.
The app-level subtitle now describes both Slide Generation and Matrix
Generation ("Design polished slide carousels or explore ideas as visual
concept matrices."). The Slide card description is simplified back to a
concise carousel-focused line without the Instagram specificity.

Replaced "Transform drafts into carousels" with "Slides and concept matrices, AI-powered" so the persistent app header no longer implies Lucid is carousel-only. https://claude.ai/code/session_0188EvRkkj6RFujggzp2bean
Reverts the subtitle change in ModeSelector — the Header tagline update was the intended fix. https://claude.ai/code/session_0188EvRkkj6RFujggzp2bean
The previous description incorrectly implied templates are configured via the project Settings modal. Templates are edited directly in the Templates panel: select a template, use the General/Style/Image/ Instructions/Prompts tabs, click Save Template. https://claude.ai/code/session_0188EvRkkj6RFujggzp2bean

Summary
This PR introduces a new Matrix Generation mode to Lucid alongside the existing carousel pipeline, along with comprehensive documentation updates. The Matrix Generator creates n×n (or rectangular) visual concept grids where each cell represents the intersection of two axes, with support for theme-based or description-based generation modes, streaming cell generation via SSE, image generation, and revalidation workflows.
Key Changes
New Features
Matrix Generation Mode: Fully independent creation mode with its own home screen, project list, settings, and views
Streaming Cell Generation: Cells populate in real-time via SSE as they complete, with status tracking (Pending → Generating → Complete/Failed)
Image Generation: Optional per-cell background images generated from AI-written prompts, with per-cell regeneration support
Revalidation Workflow: Identifies and regenerates failed or weak cells with optional user comments injected into validator prompts
Three Matrix Views:
Matrix Settings: Persistent configuration in
matrix_settings.jsonfor models, temperatures (diagonal/axes/cell/validation), concurrency limits, and retry countsDocumentation Updates
README.md: Restructured to cover both Slide Generation and Matrix Generation as first-class features
docs/user-guide.md: Complete rewrite to cover both modes
frontend/src/components/ModeSelector.tsx: Updated copy to reflect new Matrix Generation mode
