# S-00 Slide Brief V1

## Status

- Line: production-light
- Running mode: prompt and generate
- Review mode: none
- Write policy: append-only; overwrite allowed: no
- Version resolved by folder scan: `s00-v1`
- Design gate: passed by user

## Source Basis

- `slides/s00/s00-v1-design.md`: approved Chinese cover design and post-production guide.
- `slides/s00/s00-v1-design-en.md`: English companion design draft.
- `intake-repair/fix-title-2026-06-25-cover-design/阶段五-封面设计骨架.fixed.md`: repaired GPT cover skeleton used as concept source.
- `slides/slides.md`: production state table to be updated after generation.
- `visual-system/style/style-prompt-master.md`
- `visual-system/characters/character-reference-registry.md`

## Slide Function

`S-00` is the textless MV cover base. It must carry the whole film's visual promise before the first story shot: muddy road, broken starlight, a small back-view traveler, and one restrained distant fire. It is not a normal narrative frame and not a finished text poster.

## First Read

Dark wet muddy road and puddle first; broken cold star reflection second; tiny traveler walking away third; distant fire last. The upper dark negative space must remain usable for manual post-production title placement.

## Risk Class

cover image, mixed C/D motif, distant character identity, post-production safe-area requirement

## Reference Plan

- Style module: mixed C / Muddy Starlight and D / Night Road Fire, with the global road-film kernel.
- Active style references:

  - `projects/2026-06-23-在路上/intake/imgs/D.夜路篝火型蓝图.png`
- Accepted prior shot references for continuity only, not as direct copy targets:

- Visible-context roles for generation:
  - Image 1 = master character anchor for outfit, backpack, and identity continuity.
  - Image 2 = walking-back crop for posture and back-view silhouette.
  - Image 3 = repaired C muddy starlight reference for puddle texture and broken star reflection.
  - Image 4 = D night-road fire reference for restrained distant warm signal.

## Visual Requirements

- 16:9 horizontal photorealistic cinematic documentary still.
- Textless base image only: no generated title, subtitle, logo, watermark, or readable sign.
- Foreground: real wet muddy road and irregular puddle in the lower 25%-35% of the frame.
- Puddle: broken cold-white star reflection visible inside dark dirty water, fragmented by mud, ripples, stones, and road grit.
- Midground: one small 50-year-old male traveler walking away or three-quarter away, dark long coat, old backpack, old boots.
- Traveler scale: about 1/10 to 1/8 of frame height, smaller than the road and world.
- Road: starts near the foreground and recedes toward the distant fire.
- Distance: one tiny restrained warm-orange roadside fire, with at most one or two weaker far fire points.
- Upper area: dark, quiet, visually clean negative space suitable for later manual title placement.

## Character Handling

Use the current active character anchor and walking-back crop/slice. Identity should read through silhouette, long dark coat, backpack shape, walking direction, and road-worn posture. Do not show a face or make the traveler a portrait subject.

## Composition / Scale

Wide road-film cover frame. Keep environment first, road second, puddle/starlight third, traveler fourth, fire fifth. The traveler should sit below or near the middle third, small enough to remain a coordinate in the landscape. The fire should be small and distant, not a camp scene and not the destination.

## Light / Color / Texture

Low-saturation deep blue-black night, wet dark blue-gray, earth brown mud, coal black coat, cold-white reflected stars, and one restrained warm-orange fire signal. Mud, water, stones, road grit, coat fabric, backpack wear, and boot edges should feel physically real.

## Forbidden Drift

No generated text, Chinese characters, English characters, subtitle, title, logo, watermark, UI, readable sign, poster layout, hero backshot, centered large person, face close-up, travel advertisement, camping lifestyle, tents, chairs, cookware, group reunion, victory, arrival, fantasy magic glow, cyberpunk, neon, bright sunrise, bright sunset, clean tourist road, clean mirror lake, or full S-46/S-51 duplication.

## Acceptance Checklist

- Image is textless and usable as a cover base for later manual title design.
- First read is muddy night road and puddle, not a large person or campfire.
- Broken star reflection is visible but not a full close-up repetition of `S-46`.
- Traveler is small, walking away, and anchored to the active character references.
- Distant fire is tiny and restrained, not a campsite or final reunion.
- Upper dark negative space remains available for title placement.
- Output may be recorded as production-pass under the production-stage default.

## Prompt Handoff

Build the final prompt through the `gpt-image-2` Advisor / host-native workflow. Load the active character anchor and walking-back crop/slice before generation, plus the C muddy starlight and D night-road fire style references. Save selected host output as `projects/2026-06-23-在路上/slides/s00/s00-v1-image.png` and update `slides/slides.md`.
