This whole site is the demo. Every page you're looking at — the sidenotes, the post archive, the tag pages, this very paragraph — is LTheme running on real (if placeholder) content, not a screenshot or a design mockup.
If you want to see it for yourself instead of taking my word for it: click around. Try a post with sidenotes, resize the window to see the mobile layout collapse, or check how it's put together and run it locally in five minutes.

git clone https://github.com/max-ayn/ltheme-vitepress
cd ltheme-vitepress
pnpm install
pnpm docs:devThat's it — no build step to inspect, no compiled output to reverse-engineer. What you see in the browser is what's in src/theme.
