/* ============================================================
   styles.css — "Noche" design system (v2.0.0)
   C base (aurora violet/teal, near-black, refined serif + geometric
   sans) fused with A's idea: semantic CATEGORY colors, pulled into
   the Noche family so the eye always knows what zone it's in.

   Architecture: existing component CSS references semantic names
   (--bg, --surface, --accent, --good, --hairline...). We keep those
   names and remap their VALUES, so the redesign is a token swap.
   New system tokens (--brand-*, --cat-*, --space-*, --text-*) layer
   on top for the redesigned pieces.
