When a series starts to drift, the model usually takes the blame. The record tells a different story: the character was re-described from memory at every sitting, and memory quietly edits as it goes. The fix is clerical. Decide her once, write her down on a parlor card, and paste that text instead of retyping it.
Five fixed lines, always in the same order
A working parlor card holds five things. Age — a plain number, and here an adult one. Hair — colour, length, one habitual style. Build — two or three words at most. Face — one or two details that survive every crop. Signature — the small mark that identifies her even in a tight frame. Everything else lives on the changing line: outfit, room, hour, light, pose. Changing lines are supposed to change. Card lines are not.
Write the lines plainly and positively; concrete description survives generation, while a mood is reinterpreted at every attempt. Version the parlor card: when she is deliberately restyled, save the new wording as version two with a date, so an earlier set can still be remade exactly.
Working from the parlor card
Pair the parlor card with changing lines that share one setting and one light, generate at the standard cost of 6 credits, and keep the best third. Spend on edits, swaps and upscales only after the cull. When a frame comes back wrong, the cause is nearly always visible on the card itself: a changing line contradicted a card line, or a line was too vague to hold her.
What a parlor card cannot do
It cannot hold a character who was never decided. Decide her on paper first. The parlor card is not where the imagination happens; it is where the imagination is kept, frame after frame.
