[BUG] Printing a published Artifact via the claude.ai viewer silently truncates content instead of paginating

What's Wrong?

Printing (or "Print to PDF") a published Artifact from its claude.ai/code/artifact/... page cuts off content partway through the document with no warning, instead of flowing the full document across multiple printed pages. The content isn't just badly paginated — it's missing entirely from the printed output, even though it's fully present and scrollable on screen.

What Should Happen?

The full document should paginate normally across as many pages as needed, the same way it would if the raw HTML file were opened directly (not through the claude.ai wrapper) and printed.

Steps to Reproduce

Publish a long HTML artifact (long enough to require several printed pages — ours was ~9 pages of a multi-section report).
Open the published artifact via its claude.ai URL in Chrome.
Print the page (Ctrl+P) or save as PDF.
Compare the printed/PDF output to the on-screen content.
