/* ==========================================================================
   GLightbox skin for SUSCO csr.asp
   Reproduces the ekko-lightbox (Bootstrap modal) look:
   - dimmed backdrop
   - photo inside a WHITE rounded frame with a soft shadow
   - close "x" INSIDE the image (top-right), always visible
   - prev/next chevrons INSIDE the image (vertically centred), shown on HOVER
   The close/prev/next buttons are moved into .gslide-media by JS in csr.asp,
   so these rules position them relative to the photo, not the viewport.
   Load AFTER glightbox.min.css.
