A minimalist, modern favicon/app icon for a structural engineering plugin called "PEB Optimizer". The design should be a clean, scalable vector graphic (SVG) on a transparent background, utilizing a professional engineering color palette (such as deep charcoal, industrial blue, and a vibrant accent color like electric teal or safety orange). The central icon must visually combine two concepts: A sleek, stylized tapered steel I-beam cross-section or profile (representing Pre-Engineered Buildings). A subtle optimization motif integrated into the beam—such as a data graph line peaking perfectly, a spark/node of algorithmic precision, or an elegant reduction arrow showing structural thinning/efficiency. The overall aesthetic must be geometric, high-tech, and sharp, instantly conveying structural strength, weight reduction, and advanced computation. No text. Simple, bold lines optimized for crisp viewing at micro-scales (16x16 or 32x32 pixels).

The image shows a white background with the text "peb optimizer" and a logo. The logo is a blue circle with a white outline and a white "P" in the center. The text is written in a bold, black font.
