   Fifty Bucks POS — app stylesheet

/* ------------------------------------------------------------- tokens ----
   Palette sampled straight from the 50 Bucks Café logo:
     orange #FA8107 · green #5CC531 · plate #090909
   The pure logo hues stay for artwork, gradients and dark-mode fills. Solid
   controls that carry text use a deeper step of the same hue so white (light)
   or near-black (dark) label text clears WCAG AA.                            */
