Rebuilt the OS shell with a boot sequence, styled top bar with a live clock, and a glowing welcome window. Split the code into separate HTML/CSS/JS files. Hit and fixed several real bugs along the way, a missing closing div tag that was silently hiding my entire desktop, a backwards logical condition (if (!clockElement)) that broke the clock, a missing # in an SVG gradient that turned my logo black, and a conflicting overflow: hidden that killed my scrollbar. All fixed now and working smoothly
