   tap.yourcyber.guru — Marc Cohen NFC landing page — V2
   Tokens follow TrendAI Brand Guidelines 2026 v1.0.

   This is V1's stylesheet with additions for the Revision 2 content. Every
   measured value from V1 is unchanged: the tint ladder, the 3.9:1 interactive
   border, the amber focus ring with its 3px offset, the 56px tap targets,
   the 10px radius, and the prefers-contrast / forced-colors / print modes.
   Ratios are recorded in docs/test-results.md. Do not introduce a pairing
   that is not listed there.

   V2 additions are marked "V2:".
