Shareable project links

Added

• Shareable project links for Pro accounts.
• A project share page that lists the active HTML files in that project.
• Project sharing controls in the dashboard project settings.
• API and MCP support for creating one project link from related HTML outputs.

Improved

• Agents can now publish several related HTML files into one project and return a single share link.
• Project share pages stay inside BinHTML chrome and only list active unlisted artifacts.
• Project share links are noindex and can be disabled at any time.

Why it matters

When an agent creates multiple reports, mockups, design options, or explainers, you can now share the whole set as one tidy BinHTML project link.
