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

1. 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

1. 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

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

1. 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."
