/* ==========================================================================
   FGX — Portfolio (portfolio/index.html)
   Builds on /assets/fgx/fgx-type.css (fonts + fluid type scale) and
   ui-ux.css (tokens, grid, buttons, theme switching, shared modules).
   Portfolio-only modules:
     FGX-PF-01 hero + film strip        FGX-PF-03 filterable index (index / gallery)
     FGX-PF-02 featured, expanding frames           + cursor preview
   The index is plain HTML: add a <li class="pf-item"> and everything
   (numbering, totals, filter counts, gallery rhythm) follows.
