   Gybio — themes/blockparty.css   (V2.5 "Block Party")
   A PLAYFUL evolution of Brickyard: a celebration of stacked
   colour blocks. Tilted colour-block bands, abstract rows of
   rounded "blocks" as section toppers, a colourful tile wall,
   fat pill buttons that pop, and stud-dot motifs everywhere.
   Everything scoped under .v-blockparty so it can't leak.
   No LEGO trade dress — abstract rounded rects + plain circles
   + bright colours only. Text stays upright and AA-legible.
