   NOVATECH SOLUTIONS — DESIGN SYSTEM
   Signature: the "Nova Core" — a layered radial burst used in the hero,
   the page loader, and as a small pulsing motif beside section eyebrows.
   Palette: deep-space indigo + warm ember + cool cyan (not the generic
   cream/terracotta or near-black/acid-green defaults).
