in the grading table opens a modal. The modal displays an AI-generated summary of the student's strengths and areas for
improvement.
Interaction: Click the "Analyze" button. The system constructs a prompt with the student's data, calls the Gemini API,
and displays the result in a modal.
Justification: This is a powerful, high-impact feature that directly leverages AI to reduce teacher workload and provide
personalized feedback, as discussed with the user. It's a key differentiator for the application.
Library/Method: HTML (for modal), Alpine.js (for state and API call), Gemini API (fetch).
2. Report Info: Theme Selector.
Goal: Allow personalization.
Viz/Presentation: A grid of theme swatches/previews on the "Settings" page.
Interaction: Clicking a swatch instantly applies the new theme (background, sidebar colors, etc.) across the entire
application.
Justification: Directly implements the user's primary request for V5, d

<!-- Chosen Palette: Dynamic Theming Engine -->
<!-- Application Structure Plan:
This V5 "Final" prototype builds upon the solid foundation of V4 and introduces a key user-requested feature: a dynamic theming system.
1. Core Layout: The professional dark-themed dashboard layout with a persistent, hierarchical sidebar from V4 is maintained as the default.
2. New "Settings" Module: A dedicated settings page is added. Its primary function is to house the new theme selector.
3. Dynamic Theming Engine: A JavaScript-driven system allows the user to change the application's entire color scheme and background in real-time. This includes support for solid colors, gradients, and background images.
Rationale: The goal is to create an emotionally engaging and less static application. Allowing users to personalize their workspace or allowing the administrator to set themes for special occasions (like Teacher's Day) adds significant value and addresses the user's core creative requirement. This demonstrates the system's flexibility and potential for future personalization features without altering the core application logic.
-->
<!-- Visualization & Content Choices:
This version integrates the Gemini API for AI-powered student analysis.
1. Report Info: AI Student Performance Analysis.
Goal: Provide teachers with actionable insights.
Viz/Presentation: A button next to each student's name emonstrating a powerful, creative, and user-centric feature.
Library/Method: HTML, Alpine.js for managing the active theme state and applying dynamic styles using `:style`.
3. Report Info: All other modules are now theme-aware. Their container styles are designed to work with any background, and text colors may adapt for readability. The core functionality remains identical.
Confirmation: No SVG graphics used. No Mermaid JS used. All UI elements are built with HTML and TailwindCSS, with dynamic styling powered by Alpine.js.
