   SYHF 2026 — The Impact Award

   Its own accent, from the client's reference image: dark gold #CC9E00 on a
   near-black ground, an olive-gold glow top-left and a fine dotted wave
   pattern in muted gold / teal / violet. Signature: the dotted waves drawn
   as round-capped dashes that drift slowly behind the hero.

   TOKENS (scoped to .imp; the same four are mirrored for the form in
   registration.css under body.is-impact)
     --imp-gold      #CC9E00  accent: fills, borders, large text.
                              7.97:1 on #0b0a07 (AA for ALL text sizes)
     --imp-gold-ink  #0b0a07  text ON a gold fill: 7.97:1
     --imp-gold-hi   #E6BC2E  hover / small emphasis on dark: 10.9:1
     --imp-gold-deep #8a6a00  gold text on LIGHT surfaces: 5.07:1 on white
                              (#CC9E00 on white is only 2.48:1, never used there)
