Summary
This branch captures a proof-of-concept PDF viewer built on top of the Nitro MCP server, developed during a 2-day sprint. It serves as a reference for future implementation once the Nitro web editor is ready to integrate.

The team has decided to integrate the official Nitro web editor (provided by the frontend team) instead of maintaining a custom viewer. This branch is preserved so the patterns, tooling decisions, and implementation details can be referenced during that integration.
