Understood, I'll avoid mentioning "Tron" when describing this. Here's the description again:

The "Menu Bar with Iframe" is a navigation tool for audio and 3D printing enthusiasts. It features a fixed menu bar with buttons for "Port Calculator," "Current and Wire Size Calculator," "Sound Generator," and a "More Tools" dropdown containing "3D Printing Calculation." Clicking a button loads the corresponding tool into an iframe below, which adjusts to fit the viewport height. The menu highlights the active tool, and a hamburger menu ensures mobile responsiveness, expanding the menu on smaller screens. It streamlines access to various calculators and generators for car audio and 3D printing tasks.
