   Precious Obasa — "Sunrise" direction
   Study: a bold editorial brand system — aubergine / red / dusty orange / light blue / limestone,
   a light high-contrast serif, a sunburst mark, fine line-art motifs, arched sunrise gradients,
   geometric photo collage and small rotating circular stamps.
   Every page is a colour-world poster followed by a calm limestone page.
