/* -------------------- Brain imprint (atmospheric background watermark) --------------------
   Tune the effect here:
     --brain-opacity  → overall visibility (try 0.06–0.14)
     --brain-zoom     → 1 = exactly fills the viewport, >1 zooms in further
     --brain-position → background-position of the graphic (which part
                        of the brain shows/leans into view, e.g. "72% 45%")
   The source PNG already has a transparent background (only the faint
   linework has any opacity), so this needs nothing but a plain opacity —
   no blend-mode trickery, and no risk of a visible box/rectangle. It's a
   fixed full-viewport layer so it persists behind every section as you
