/* Open Echo -- design tokens (locked from ui-ux-pro-max vintage/serif steer + avatar art sampling)
   bg: #F2DDB4 (sampled off avatar/banner edge)   bg-deep: #E7CE9C (panel field)
   ink: #1C1712 (art's thick outline)   ring: #A99E86 (sampled off the art's grey echo rings)
   accent: #8B5E34 (aged brass, copy/hover state only)
   type: Spectral (serif, hero line + labels) + Fragment Mono (ticker/countdown/CA, exact-case, copy-safe)
   spacing: 8 / 16 / 24 / 40 / 64   radius: 0 (flat like the art; the badge's circle lives in the raster)
   motion: the art's own rings continued outward as a slow looping pulse, one real countdown, one flash at 0
