   Organic blob backdrop for solo (md/lg) mascot appearances — empty
   states, error pages, hero sections. Gated on size so the small inline
   mascots in chat headers and result headings stay flat. The blob slowly
   morphs between two pseudo-random radii so the surface around Nib reads
   as alive, not a hard rectangle. Tinted with the active --pico-primary
   so it tracks admin theme overrides.
