Style guidelines:

- "Corporate": white, professional blue (#1A56DB), clean
- "Tech / Startup": dark navy (#0F172A), cyan (#06B6D4), purple (#8B5CF6)
- "Nature / Zen": warm white (#FEFDF8), green (#2D5016), amber (#B45309)
- "Académique": cream (#FFFBF5), burgundy (#7C2D12), blue (#1E40AF)
- "Minimaliste": pure white, black (#18181B), red accent (#DC2626)
- "Luxury Editorial": deep charcoal/cream, champagne gold, magazine typography, full-bleed imagery
- "McKinsey Consulting": white/ink blue, precise grids, executive charts, numbered insights
- "Cinematic Documentary": dark cinematic overlays, frame bars, photography-first, caption labels
- "Neo Futuristic": black, electric cyan/magenta, glow grids, sci-fi panels
- "Japanese Minimal Zen": warm paper, ink black, muted green, asymmetry, generous whitespace
- "Swiss Modern": white, red/black, strong grid, huge typography, brutal clarity
- "Vintage Scientific": parchment/cream, sepia, blueprint lines, diagrams, annotations
- "Premium Data Story": dark/white hybrid, hero metrics, dashboards, elegant charts

Rules:
- Content points: max 20 words each, factual and specific
- image_prompt: English, cinematic, under 30 words, NO text in image
- image_source: "ai" for generated, "web" for stock photo search
- design_pattern: choose one of cinematic_full_bleed, editorial_split, consulting_dashboard, hero_metric, timeline_ribbon, comparison_duel, image_mosaic, map_pins, quote_breathing, process_flow, card_grid, blueprint_diagram, luxury_catalog, swiss_poster
- notes: conversational tone, 2-3 sentences, like talking to audience
- icons inventory: pick from chunk-filled library (crown, shield, sword, fire, users, chart-bar, lightbulb, target, bolt, map, castle, skull, book-open, globe, rocket, heart, star, trophy, flag, clock)
- First slide layout="cover", last="closing", others mix of "content"/"comparison"/"timeline"/"quote"
- page_rhythm: "anchor" for cover/closing, "dense" for data-heavy, "breathing" for impact pages
- Reply ONLY with raw JSON, no markdown code blocks, no explanation"""

- Use fill-opacity/stop-opacity instead of rgba. Use inline attributes only.
- Images: <image href="../images/FILENAME" preserveAspectRatio="xMidYMid slice"/>

VISUAL QUALITY RULES (for premium output):
- Use <defs> with linearGradient (3-4 stops with varying stop-opacity) for rich overlays
- Use radialGradient for subtle background glows (stop-opacity="0.06" to "0")
- Use <filter> for glow effects: feGaussianBlur + feFlood + feComposite + feMerge
- Use letter-spacing="3" on category labels / section headers for editorial feel
- Use vertical accent bars: <rect x="" y="" width="4" height="30" fill="PRIMARY"/>
- Use thin separators: <rect width="200" height="1" fill="BORDER"/> between sections
- Hierarchy: hero numbers at 80-120px bold, then 24px subtitle, then 16-18px body
- Cards: rounded rects (rx="12") with subtle stroke, padding 20-30px inside
- Top-level <g id="..."> grouping for each logical section (header, content, footer)
- Page number: bottom-right, annotation size, muted color
- Add decorative circles/dots at low opacity (0.06-0.15) for visual texture
- Text must be readable: ensure contrast between text color and background
- For breathing pages: big whitespace, one dominant element, dramatic

DESIGN PATTERN LIBRARY (pick/adapt according to slide.design_pattern):
- cinematic_full_bleed: image full canvas + multi-stop dark overlay + title near bottom third + hairline accents
- editorial_split: 55/45 asymmetry, image crop on one side, text column with small caps label
- consulting_dashboard: KPI cards, microcharts, numbered insights, strict 12-column grid
- hero_metric: one huge number/word (90-140px) with glow + two supporting facts
- timeline_ribbon: horizontal or vertical progression with nodes, date tags, connector line
- comparison_duel: two opposing panels separated by thin divider, mirrored structure
- image_mosaic: 3-5 image tiles with consistent gutters + captions, magazine layout
- map_pins: map/image background with pins, labels, legend panel
- quote_breathing: huge quote, single image/texture, extreme whitespace
- process_flow: chevrons/arrows/steps with numbered circles, clear directionality
- card_grid: 3/4/6 cards with icons, accent bars, equal spacing
- blueprint_diagram: thin strokes, dashed lines, labels, technical schematic feel
- luxury_catalog: product/image hero, serif typography, gold dividers, editorial footer
- swiss_poster: huge typography, strict grid, red/black/white, minimal but striking"""

## Workflow PPT Master complet

1. **Strategist** (HY3-preview) → design_spec + spec_lock (palette, typo, icônes, rythme)
2. **Image Acquisition** → ComfyUI GPU ou recherche web
3. **Executor** (GPT-OSS-120B) → Génère chaque SVG individuellement, qualité premium
4. **Post-processing** → finalize_svg.py (icônes, images, rounded rects)
5. **Export** → svg_to_pptx.py → PPTX natif éditable

**Approche multi-modèles**: HY3 pour la planification (raisonnement), GPT-OSS-120B pour le code SVG (rapide + précis).
Le spec_lock garantit la cohérence couleurs/fonts sur l'ensemble du deck.

**Stack**: OpenRouter (2 modèles gratuits) + ComfyUI local (RTX 5070 Ti)
