Create a 9:16 experimental portrait poster with a clean editorial layout. SUBJECT: a single adult woman in three-quarter profile, one eye and cheekbone kept perfectly sharp and recognizable. EFFECT: luminous chromatic glitch trails in cyan, magenta and violet sweep horizontally across the lower face and shoulders, dissolving the edge of the figure into elegant color echoes, over a clean white background with faint fine grain. TYPOGRAPHY: custom refined minimal type — large title "SPECTRAL DRIFT", small supporting phrases "color echo", "frame memory", "light offset". MOOD: futuristic, vivid, dreamlike, design-driven. FINISH: 8k, poster-grade, strong focal point, controlled distortion.
