:Built out modular project routing across stardance.html, blog.html, and common-ground.html. Implemented a custom 3D perspective tilt engine for DOM elements using event-driven mouse coordinate mapping. Handled dynamic bounding rect recalculations (getBoundingClientRect()) to compute normalized hover offsets and apply real-time rotateX/rotateY CSS transforms. Added clean event cleanup via mouseleave listeners to instantly purge inline transform styles on blur.
