   Saizen Acuity · Sankitha Kirindu · "The standard"
   Built from his own CV: white paper and cream chapters, one gold, the CV's
   gold corner brackets. The hero is his portrait cut out of its photo and
   breaking out of a bracketed frame; the education chapter keeps its
   staircase loop. Crisp: hairlines, 2 to 4px corners, no glows, no blur.
   Colour with meaning lives only inside the engine room: emerald passed,
   amber caught, red failed.
