/* ============================================================
   DerNexus Website UI Kit — styles
   Faithful recreation of the dernexus.ca visual system,
   refined for a more immersive V2. Dark, red, Barlow + DM Sans.
   Fonts self-hosted from fonts/ (no CDN dependency).

   V2.1 additions: Alt-4 "Combined" button system (cursor bloom +
   ring glow), constellation portal labels, SphereGallery overlay,
   Proof + FAQ sections, mobile menu, and the audit fixes:
   hover states gated behind (hover:hover), :active press feedback,
   :focus-visible everywhere, charcoal-surface contrast tokens,
   reduced-motion coverage incl. smooth scroll.
