Atlas drift is usually blamed on the model. Survey the prompts instead. The woman is described from memory each evening, and memory edits as it walks: “long auburn hair” in one week becomes “reddish flowing hair” the next, and the audience watches a stranger take over the shoreline. The repair is cartographic. Write her down once, on a card you paste rather than retype, and let every frame be surveyed against it.
Five bearings, always in the same order
A working coast card holds five things. Age — a number, always 25 or over. Hair — colour, length, and the one way she usually wears it. Build — two or three words, no more. Face — one or two details that endure a change of light. Signature — the mole, the ring, the mark that survives even a tight crop. Everything else belongs to the scene line: outfit, stretch of coast, hour, pose. Scene lines are meant to change with the walk. Bearings are not.
Two habits keep the card trustworthy. Bearings are stated plainly and positively — “long auburn waves worn over one shoulder” survives generation, while “glorious hair” is re-decided at every attempt. And the card is versioned. When she is deliberately changed — a new cut for a new season of the atlas — the new text is saved as version two with a date, so an old set can still be remade exactly as it first appeared.
Working from the card
Production then becomes a pleasant walk. Pair the card with scene lines that share one stretch of shore and one sunset, and make the set at the standard model’s 6-credit fare. Keep the best third. Spend on repairs, swaps and upscales only after the cull. When a frame returns off character, run the survey: a scene line contradicted a bearing, or a bearing was too vague to hold a coastline. Both faults are fixed on paper, at the desk, not by wrestling with settings at dusk.
What a card cannot do
It cannot hold a woman who was never charted. If the bearings are adjectives — lovely, striking, perfect — no system will keep her from drifting. Decide her on paper first. The card is not where the imagination happens; it is where the imagination is kept, the way a chart keeps a coast.
