The PDF path protects29mathematics from the Markdown parser with placeholder tokens, renders in a real browser engine,30and waits for the math to appear before capture. The slide path issues a \emph{second} model call31that restructures the report into slide bodies, then compiles a branded Beamer document in two32\LaTeX{} passes. Word uses a document converter; spreadsheets carry live formulas written from the33sandbox; and any report can be published to a stable URL. One source, many auditable deliverables.}34\label{fig:docpipeline}35\end{figure}36
