   Doodles
   Small, original hand-drawn-style geometric marks (spirals, sunbursts,
   zigzags, dot clusters) scattered in the margins as a light decorative
   touch, loosely inspired by geometric motifs common across indigenous
   and African textile/art traditions — kept abstract rather than
   reproducing any specific cultural symbol. Purely decorative, hidden
   on smaller screens where there's no margin room for them.
