/* Neurologros.
   One typeface, Atkinson Hyperlegible Next, drawn for readers with low vision — the right voice for a
   practice that helps children be understood. Colours from the two logos: the brain logo's night blue
   and Academia's gold. Structure comes from space and type, not from boxes: no eyebrow labels, no
   card grid, no coloured accents inside headlines (revised Oct 24 2026 after "muy diseño Claude"). */
