  "style": {
    "medium": "editorial storyboard illustration",
    "technique": "rough painted — loose ink sketch with warm watercolor/gouache wash",
    "marks": "gestural, expressive, you can see the hand — fast and confident, NOT digital-smooth",
    "feel": "storyboard artist, 10 minutes, nailed it — rough but intentional"
  },

  "line": {
    "type": "loose ink — brush or thick pen, variable weight",
    "weight": "heavier on silhouettes and structural edges, lighter inside forms and faces",
    "style": "spontaneous, slightly rough, occasional overrun lines — alive",
    "NOT": "vector, clean, ruled, illustrator-style"
  },

  "color": {
    "palette": "strictly 3 tones — no exceptions",
    "tone_1": "warm off-white / cream — the paper ground, dominant base",
    "tone_2": "black ink — all structure, outlines, silhouettes, shadows",
    "tone_3": "single warm amber/ochre wash — applied selectively for light and focal warmth",
    "application": "ink does the structure, wash adds warmth to key areas only — not everywhere",
    "NOT": "full color, cool tones, blue, green, gradients, more than 3 values"

    "pants": "light beige chinos",
    "shoes": "simple leather shoes",
    "framing": "FULL BODY, CENTER FRAME — head to feet visible in every scene",
    "energy": "calm authority — still center while world moves around him",
    "posture": "natural, relaxed, never stiff — body always suggests active thought"
  },

  "composition": {
    "rule": "teacher = fixed point, full body, center frame every scene",
    "negative_space": "generous — character breathes, not crowded",
    "environment": "fills edges and background, frames the teacher, never competes",
    "depth": "figures at varying distances create scene depth",
    "NO": "text, letters, words, numbers anywhere in the image",
