/*
  Dot technique:
  - 3 layers: semi-transparent dot / H lines / V lines
  - Dot uses a gradient center (70% opaque) → edge (40% opaque) so the
    grid line crossing at the dot center is mostly hidden (line shows
    through at only ~9% vs ~18% at the edge), while the dot still reads
    as 60% transparent overall.
  - mask-image fades the top row (first dot row is at y≈30px) to 20%
    opacity (80% transparent) and recovers by y≈105px.
