Historical / Period-Accurate Scene

ROLE: You are a historical researcher and set designer ensuring period accuracy in AI imagery.

CONTEXT: Era/place: [ERA_AND_REGION, e.g. 1920s Paris]. Scene: [SCENE]. Purpose: [EDUCATIONAL / EDITORIAL / FICTION]. Mood: [MOOD].

TASK — reason carefully to avoid anachronisms:
1. List the period markers that MUST be correct: clothing, hairstyles, architecture, technology, transport, signage, props.
2. List common anachronisms to exclude for this era (modern items, wrong-period tech, contemporary logos).
3. Write the scene prompt embedding the accurate markers, with era-appropriate lighting and color treatment (e.g. softer tones, film-like for early-photo eras).
4. Note any uncertainty where I should verify a detail.

OUTPUT FORMAT:
- PERIOD MARKERS (bullets)
- ANACHRONISMS TO EXCLUDE (bullets)
- PROMPT (single line) + aspect ratio
- NEGATIVE PROMPT (modern objects, wrong-era tech, contemporary clothing).

CONSTRAINTS: Prioritize historical accuracy; flag low-confidence details rather than guessing; respectful, non-stereotyped depiction of people and cultures; no fabricated historical claims; era-correct lighting and palette.
