A salon regular is not recognised by luck. She is recognised because the card written at her first visit is consulted at every visit after. AI series drift for the same reason a new stylist guesses: the description was rewritten from memory at every job, and memory edits as it goes. Write her down once, on a card you paste rather than retype.
Five fixed lines, always in order
Age — a number, and in this salon a mature one. Hair — colour, length and one habitual style. Build — two or three words. Face — one or two details that endure every crop. Signature — the slide, the pin, the detail that survives a tight frame. Everything else belongs to the changing line: outfit, chair, hour, light. Changing lines are meant to change. Card lines are not.
State lines plainly and positively — concrete descriptions survive generation; adjectives are reinterpreted at every attempt. Version the card when she is deliberately changed, with a date, so an old set can be remade exactly as it was.
Working from the card
Pair the card with changing lines that share one room and one light, generate at the standard 6-credit cost, and keep the best third. Spend on repairs, transfers and upscales only after the cull. A frame that returns off character almost always traces back to the card: a contradiction, or a line too vague to hold her.
What a card cannot do
It cannot hold a muse who was never decided. Decide her on paper first; the card is where the decision is kept, visit after visit.
