   Button colour system — three tiers only. Sizing, padding,

     .btn-gradient  GRADIENT  (3-btn: 2nd)
     .btn-light     LIGHT     (2-btn: 2nd)

   In dark mode the DARK tier becomes an elevated dark surface rather than
   near-black — a literally near-black button would vanish against the dark
   page — and the LIGHT tier becomes near-white, so all three tiers stay
   visually distinct in both themes.
