/* Waterfall Bank — Employee vCard & QR Generator
   Palette sampled from the supplied bank mark (RGB 8,97,206) plus a
   deep navy for text and a cool off-white background. The vertical
   "waterfall" stripes from the logo are reused as a recurring motif
   (card left-borders, section dividers) so the tool visually belongs
   to the brand rather than looking like a generic admin form. */
