   Mycelium - design tokens (locked)

   palette, sampled off the approved avatar (chrome tubes on a black void):
     void       #050608  page background, matches the art's own black
     chrome-lo  #0a141c  tube base shadow pass
     chrome-mid #5f83a3  tube body, sampled off the cap's mid-tone
     chrome-hi  #e2f1fc  specular streak, sampled near the cap highlight
     lime       #ccff00  robinhood chain accent - a thin glow on some
                          threads and the copied-state flash only, never
                          a fill, per the batch-wide accent-only rule
     mist       #93a6b4  small print / annotations

   type: Michroma (display - the tagline, the node label, the HUD chips;
         a single-weight geometric face with a metallic 90s-tech read,
         unclaimed elsewhere this batch) + PT Mono (CA, depth readout,
         annotations - real case, always copyable)
   spacing: generous, the network itself is the layout - text sits in a
            handful of fixed spots, not a grid
   radius: 3px, just enough to soften a button edge; the tubes carry all
           the curvature this site needs
   motion: a chevron bob inviting the first scroll, starlight twinkle,
           and a few lime signal pulses that keep travelling down chosen
           root paths the whole time you are on the page - the tubes
           themselves never move, only what runs through them does
