Posters and other PDFs shown as a preview card on /Publications/.

To add one:

1. drop the PDF here, e.g. ISC26_Poster.pdf
2. bin/pdf-preview assets/posters/ISC26_Poster.pdf (writes ISC26_Poster.jpg next to it)
3. reference both from _pages/Work.md:

The include renders nothing until the PDF actually exists, so an unfinished entry never shows a broken image on the live site.

Poster PDFs exported from Illustrator or Inkscape are often 50-200MB. Git keeps every binary forever, so shrink it first, e.g.

gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH \
   -sOutputFile=small.pdf big.pdf
