The lightest notes app implementation in 111 loc

I wanted to see how far I could go building a notes app using only what modern browsers already provide – no frameworks, no storage APIs, no build step.
What it does:

Single HTML file, no deps, 111 loc
Notes live in the URL hash (shareable links!)
Auto-compressed with CompressionStream
Plain-text editor (contenteditable)
History support
Page title from first # heading
Respects light/dark mode
No storage, cookies, or tracking

The entire app is the page source.
