Shruti
Her base reference image is the identity anchor. Replace it only when you have a better full body shot — her description rewrites itself from whatever image is there.
Base reference image
Everything you write here lands in the image — build, glasses, age, colouring. Be specific.
Description
Written from the reference image and stored, so her face and body stay the same across every generation. Edit it if anything reads wrong.
Styling and persona. Steers wardrobe and setting when an inspiration image is adapted. Leave it blank and the idea alone decides.
