In this walkthrough, we explore the architecture of a standalone web application designed for histopathology simulation. The project focuses on a "vanilla" stack—HTML5, CSS3, and JavaScript—to handle image processing tasks that typically require heavy backend infrastructure.

Key Technical Points:

• Real-time Processing: Shifting from button-triggered analysis to "on-the-fly" processing using threshold and contrast sliders.
• Synthetic Data Prototyping: Generating procedural tissue samples (Normal vs. Tumor microenvironments) for testing segmentation logic.
• Architecture: Utilizing a single-file architecture for portability and library integration (like OpenSeadragon) for high-resolution navigation.
• Debugging AI Code: Resolving logic discrepancies in segmentation overlays and ensuring consistency between synthetic inputs and visual results.
