Проблема: VISUAL CONCEPT и STYLE из COVER_STYLES противоречили друг другу
  (sculptor on marble + frosted glass style = модель рисовала свой дефолт)

Решение: 3 простых параметра на статью без конфликтов:
  SUBJECT: что изображено (из getVisualMetaphor)
  SETTING: антураж (12 вариантов по articleId % 12):
    oak desk | marble | slate | workbench | velvet | dawn mist |
    terracotta | city night | concrete | library | frost | brick
  LIGHTING: конкретный свет (golden hour, studio, rim light, etc.)
  COLOR TEMPERATURE: warm amber / cool whites / etc.

Убраны STYLE/PALETTE/MOOD/COMPOSITION блоки которые путали модель.
Теперь каждая статья = уникальная физическая сцена с конкретным светом.
