Bartosz OsiejA web OS that 'never booted': the two bugs that looked like kernel failures but were 404s and z-index
Aurora (a browser-based OS) stuck on 'Initializing kernel…' for days. The kernel was fine — the bundles were 404ing from GitHub Pages, and then desktop icons refused clicks because of one CSS line. Post-mortem.

Daniel PertuTwenty four strings got their own file, because one import cost every page 100 KB
A client component in the root layout needed a list of slugs. It was importing them from a 4,400 line module, so the whole catalogue shipped to the login page.
