/* First payment, with confidence — tiun onboarding concept.
   The product follows tiun's own light look (white surfaces, black pill actions, violet bolt).
   Prototype controls use a white, mono look with a blue accent (never the product's violet), so they never read as product.
   Tokens are design choices for this concept, not extracted tiun tokens. */
