Build a single-file 3D Universe Simulator with Canvas and JS

Overview: Build a production-ready, single-file interactive 3D Universe Simulator using HTML5 Canvas and JavaScript without any external libraries or CDN dependencies. Key Specifications: Interface & Search: Full-viewport minimalist glassmorphism interface featuring a top header bar (real-time search engine with autocomplete dropdown, FPS counter, active target indicator) and a bottom control deck (focus shortcut buttons for Black Hole, Galaxy, Sol System, Terra, Zeus, and a 0x-5x time warp slider). Live search filters celestial targets as you type, automatically panning and zooming the camera to selected targets upon selection. Graphics & Physics: Custom pure JavaScript 3D projection engine (project(x, y, z)) rendering 8,000+ dynamic spiral galaxy stars with color variations, a central supermassive black hole with an accretion disk and event horizon, and an orbiting planetary solar system with real-time speed adjustments. Includes full mouse controls (drag to orbit/rotate camera, scroll to zoom).
