/* ============================================================
   Nanu marketing site — design tokens
   Concept: "Built on patterns." Nanu's own product is grounded in
   repetitive-pattern recognition (the entry requirement for its
   first learners, and the literal technique behind Beadwork
   Academy). The bead-row motif that recurs through this site is
   not decoration bolted onto a template — it's the same visual
   language the product teaches.

   Committed single-theme, light, blue accents (not auto dark
   mode) — the palette is three shades of blue rather than three
   hues, so the bead-row rhythm still reads as pattern/variation
   while staying inside one deliberate color family.
