Quarto Slides (RevealJS) projects compile to output.html, not output.pdf, so the existing "Download PDF" button was meaningless for them. Replace it with a two-option dropdown matching the editor's PdfHybridDownloadButton: - Desktop (ActionsCell): icon button opens a dropup with "Download standalone HTML" and "Download PDF slides" - Mobile (ActionsDropdown): two separate dropdown items with the same choices and per-format spinner while the export is in progress Both use the same /project/:id/presentation-export/:format endpoint and show a loading modal (with error reporting) during the server-side render, exactly as the editor toolbar does. Non-RevealJS projects continue to show the compile-and-download-PDF button unchanged. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
