/* Deep-green aurora echoing the app dashboard. A broad wash casts the whole page
   in green, then brighter curtains bleed in from the edges. Every gradient center
   is pushed off-screen (50% -20%, 8% -12%, 112% 4%, …) so only a soft arc shows,
   never a full circle — a centered orb is exactly what got the old green glow
   removed for reading as a half-orb/globe. A faint warm ember stays bottom-right
   for brand balance. The layer is oversized (inset: -15%) so the slow drift never
