No LaTeX engine found (looked for latexmk, tectonic, pdflatex).

Figures (report/figures/*.pdf) and tables (report/tables/*.tex) were still
regenerated, so report.tex is ready to compile anywhere. To build the PDF:

  Windows   winget install MiKTeX.MiKTeX
  macOS     brew install --cask mactex-no-gui
  Debian    sudo apt install texlive-latex-recommended texlive-fonts-recommended
  Anywhere  cargo install tectonic     (single binary, fetches packages itself)

Or upload report/ to Overleaf and compile there — it is self-contained.
