Demo and product page for Klarbild

A static Astro page. The sheet playground imports the print engine
(printlayout.ts, paper.ts) verbatim from the Klarbild repository and runs it in
the browser, so the layout on screen is the application's own arithmetic rather
than a mock-up. The PDF it offers is drawn from the same placements with pdf-lib.

No backend, nothing uploaded, no third-party requests.
