Ink Wash Ronin Cinematic Film

You are an expert creative technologist specializing in generative art and cinematic code. Build a complete, production-ready 90-second animated film that renders every frame as a living Japanese sumi-e ink painting.

## FILM CONCEPT
{{film-concept}}

## TECHNICAL REQUIREMENTS

**Visual Style — Sumi-e Ink Aesthetics**
- Every frame must look hand-painted with traditional Japanese ink wash techniques
- Implement authentic ink bleeding, brush stroke variance, and water diffusion effects
- Use grayscale with occasional subtle sepia tones; paper texture visible
- Dynamic ink density: thin washes for atmosphere, bold strokes for subjects
- Particles and flow fields to simulate ink dispersing in water
- NO photo-realism, NO hard edges — embrace organic imperfection and negative space

**Camera & Cinematography**
- Third-person cinematic camera with smooth, purposeful movement
- 90-second runtime (target 30 or 60 fps based on performance)
- Scene composition inspired by ukiyo-e: asymmetric balance, depth through layering
- Camera should feel like a brush painting the world into existence as it moves

**Animation & Pacing**
- Fast-paced visual storytelling with clear narrative beats
- Elements should emerge and fade like ink blooming on wet paper
- Choreograph at least 3-5 distinct story moments or scene transitions
- Time the entire arc to conclude naturally at 90 seconds

## CODE STRUCTURE

Provide complete, well-organized code with:

1. **Setup & Configuration**
   - Canvas/viewport initialization
   - Timing system (frame counter, elapsed time, scene markers)
   - Performance optimization flags

2. **Ink Rendering System**
   - Particle systems or shader-based ink simulation
   - Brush stroke generator with pressure/speed variation
   - Paper texture and bleed effects
   - Layering system (background wash → midground → foreground strokes)

3. **Scene Management**
   - Timeline controller mapping 0-90 seconds to story beats
   - Smooth transitions between narrative moments
   - Camera path and easing functions

4. **Character/Subject Animation** (if applicable)
   - Procedural or keyframe-based movement
   - Ink stroke trails following motion
   - Expressive poses that read clearly in silhouette

5. **Audio Sync Points** (code comments)
   - Mark timestamps where sound effects or music cues should trigger
   - Suggest atmospheric audio (shakuhachi flute, taiko drums, wind, silence)

## DELIVERABLES

- **Fully functional code** ready to run in {{target-platform}}
- Inline comments explaining the narrative arc and key visual techniques
- Configuration constants at the top for easy tweaking (ink density, camera speed, scene durations)
- Performance notes and optimization tips
- Brief artist's statement (as code comment) explaining the emotional journey

## CONSTRAINTS

- Must run at acceptable frame rate (aim for 30fps minimum)
- Code should be self-contained or use only widely-available libraries
- Total runtime locked at 90 seconds — pace accordingly
- Prioritize evocative mood over photographic detail

Deliver code that is both technically excellent and emotionally resonant — a film that honors the wabi-sabi philosophy of finding beauty in impermanence and imperfection.
