   holographic.css — the calling-card aesthetic, turned up.

   Layers glassmorphism + holographic iridescence over the dark base in
   style.css. Loaded on the personal-site landing (index.html). The
   shared nav glass lives in site-nav.css so it stays consistent
   site-wide; the heavy treatment (aurora, glass cards, holographic
   headers) is scoped to whichever page links this file.

   Palette is the coordinated spectrum already used as accent across the
   Historical Apoplexy pages — cyan, blue, violet, pink, gold, mint —
   here promoted from accent to signature.
