/* ==========================================================================
   KAIZEN AFFILIATE — kaizenaffiliate.co
   Concept: "改善 ANNUAL STATEMENT — The Compounding Ledger"
   Paper & ink annual report; typography is the only decoration.

   RED BUDGET — #A31621 (hanko red) appears at most SEVEN times per full page:
     1. nav CTA button          2. hero primary CTA button
     3. hero equation result    4. contact hanko seal stamp
     5. hanko submit button     6. footer seal
     7. diligence-pack offer line
   Links/focus use red only as a *state* (hover/focus), not a resting color.
   On the ink slab, red text uses the lighter tint #E0684F (5.5:1 on ink).
