Three honest notes
Accessibility shows up twice on purpose — labels and alt text as a beginner habit, ARIA patterns and keyboard traps as an advanced skill once the basics are automatic.
Forms get their own beginner AND intermediate chapter because native form validation alone quietly replaces a surprising amount of JavaScript.
Web components and the parsing algorithm are the deepest, most-skipped layer — most people who write HTML daily never need them, but the advanced tier doesn't skip them.
