A boundary post does its work by staying where it was staked. Move it a little each season and the plot it marks is a different plot every year. A character’s description behaves the same way: rewritten from memory at every job, it is re-staked by mood each time, and the series slowly works ground that was never hers. Written once on a plot card and staked at the post, the lines hold.
The card stakes five lines in fixed order. Age, a plain number. Hair — colour, length, one habitual style. Build in two or three words. Face — one or two enduring details. Signature — the detail that survives a tight crop. Inside those lines sits the day’s work: outfit, bench, hour, light — free to change at every sitting, because the boundaries around it do not.
Paste the card word for word at the head of every prompt. Generate at the standard 6 credits and keep the best third. Repairs, swaps and upscales are spent only inside the lines — on frames judging has passed against the card.
Good fences are not restrictions here. They are what makes the inside of the plot worth working, sitting after sitting.
