   bg: rgb(161,225,52) #a1e134, the exact flat acid-green sampled off assets/avatar.png
   ink: #000 pure black, matches the art's own linework
   type: Permanent Marker (crude mouse-scrawl label/ticker/copy, matches the "MS Paint scrawl" lane)
         Space Mono (the CA only - real case, copyable, per the hard CA rule)
   corner radius: 0 everywhere except the CA chip (2px, just enough to read as a UI control)
   motion: two signal pings loop outward from the whisker-antenna arcs already drawn in the art.
           prefers-reduced-motion kills them.
