/*
  Design concept: "dark, modern, bold" - a neutral near-black canvas with
  elevated dark-grey cards (no hard borders; separation comes from a soft
  shadow plus a very subtle 1px edge, not a visible outline), generously
  rounded corners, and bold, large-scale headline typography. Replaced an
  earlier "darkroom" concept (a green-tinted near-black with sharp 3px
  corners and visible panel borders) that read as more utilitarian/retro
  than modern. The signature teal accent carries over unchanged - it was
  never the problem, the neutral-vs-green cast and the sharp edges were.
