   Light and cool, built like a working console rather than an editorial page:
   glass panels on cloud white, blueprint grids, live components.
   Colour carries one meaning everywhere on the page:
     blue    = an agent acting        gold  = a human decision
     emerald = checked / verified     coral = blocked / risk
