   JD CAPITAL GROUP — PROJECTS PAGE
   Light, white-based case studies with a premium image
   carousel. Images are presented, never edited — the original
   files are shown as provided, at proper (non-stretched) sizes.
   The full-screen lightbox stays dark intentionally: a dark
   viewing stage is what makes photography read best when
   enlarged, regardless of the page's own light theme.
