Wrapping up IronManOS. Added the last piece - a Suit HUD app with live power diagnostics, a spinning arc reactor tied to the reactor readout, animated radar, and a boot sequence that reveals each panel in turn. Wrote a proper README and pushed everything live on GitHub Pages: https://raczjonathan12.github.io/.
This was my first time hand-coding HTML from scratch - no framework, no tutorial copy-paste. Building something this involved (animations, live data updates, a working desktop-style OS) while learning the language at the same time was the real challenge.
