Generate Figures Gallery

Create an HTML gallery page displaying all project figures with their captions and source notebooks.

Steps

1. Scan images/ for all image files:

   • Supported formats: .png, .jpg, .jpeg, .svg, .pdf
   • Record each file's name, path, and modification date

2. Scan all registered notebooks (from _quarto.yml) for cells with fig- labels:

   • Extract the cell label (e.g., fig-sample, fig-event-study)
   • Extract the caption from #| fig-cap: or *| fig-cap: directives
   • Record the source notebook path

3. Generate an HTML gallery page with:

   • A title and generation timestamp
   • For each figure from images/:
     • Image thumbnail (or placeholder for PDFs)
     • Filename as caption
     • File size and dimensions (if determinable)
   • For each figure from notebooks:
     • The cell label
     • The caption (from cell directive)
     • The source notebook name
     • The embed shortcode: {{< embed notebooks/<name>.ipynb#<label> >}}
   • Simple CSS styling for a grid layout

4. Save the gallery to _manuscript/figures-gallery.html (the _manuscript/ directory is gitignored, so this output won't be committed).

5. Report:

   • File path to the gallery
   • Count of figures from images/
   • Count of figure cells from notebooks
   • Command to open: open _manuscript/figures-gallery.html

Error handling

• If images/ does not exist or is empty, note it and continue with notebook figures.
• If no notebooks have fig- labeled cells, note it and continue with images/ files.
• If both sources are empty, report "No figures found in the project."
