  "A1_PURPOSE": {
    "description": "Encodes the visual DNA of Data Journalism and Narrative Data Visualization (2008–2025) as a deployable infographic style system. Draws from The New York Times Graphics desk (Amanda Cox, Kevin Quealy), The Guardian Datablog, Financial Times chart grammar (John Burn-Murdoch), The Pudding essay-form scrollytelling, Edward Tufte's data-ink ratio principles, and the D3.js open-source visualization tradition. THE MOST EPISTEMICALLY RIGOROUS HIS-V STYLE — data journalism demands source attribution, uncertainty visualization, context annotation, and evidence-graded claims. Ideal for any historical topic where evidence quality matters.",

  "A3_CORE_OBJECTIVE": {
    "main_task": "Apply Data Journalism visual style to HIS-T output — annotated chart as primary element, context notes embedded in visualization, source attribution rigorous, uncertainty/confidence levels visible",

        "What sub-style? (NYT narrative annotation | FT chart grammar | The Pudding essay | Edward Tufte sparkline | Guardian Datablog evidence grid)"
      ]
    },
    "step_2": "PARSE content → MAP to data journalism zones: narrative headline (makes specific claim), chart body (data-ink maximized), direct annotation layer (context notes on chart elements), source footnotes, uncertainty indicators",
    "step_3": "APPLY minimal editorial palette: white ground, single accent color, gray annotation text, black primary data",
    "step_4": "MAP components per A8, applying Tufte data-ink ratio principle to every element",
    "step_5": "GENERATE render spec + prompt referencing NYT Graphics How the Virus Got Out, FT John Burn-Murdoch COVID charts, The Pudding film dialogue analysis, Tufte Visual Display of Quantitative Information"
