S-20 Slide Brief V2

Status

• Status: ready for one-shot worker.
• Slide: S-20.
• Version: s20-v2.
• Review: none / intentionally suppressed.
• Overwrite allowed: no.

Source Basis

• Source shot skeleton: S-20: 那一簇火 / 微弱支撑.
• Core direction: the small fire is closer than S-19 and lights only a small patch of mud and stones; traveler remains at the frame edge.

Slide Function

Show the fire has temperature, but not liveliness. It supports the road emotionally without becoming a camp or rest scene.

First Read

Small firelit mud/stones first, surrounding night road second, frame-edge traveler last.

Risk Class

• distant human
• core motif

Reference Plan

• Style module: D / Night Road Fire with mud/stone detail.
• Active style references:
  • projects/2026-06-23-在路上/visual-system/style/style-anchor-board-v1.png as common A/B/C/D calibration board.
  • projects/2026-06-23-在路上/intake/imgs/D.夜路篝火型蓝图.png as D firelight reference.
• Sequence continuity:
  • Use S-19/s19-v2 only if it exists before this worker launches; otherwise rely on D style master.
• Historical contrast:
  • projects/2026-06-23-在路上/slides/s20/s20-v1-image.png is broad-run historical evidence only, not an accepted final.
• Character references: none by design. Traveler remains at edge and identity detail should not drive the shot.

Visual Requirements

• 16:9 horizontal cinematic documentary road-film still.
• Fire closer than S-19 but still small and restrained.
• Warm orange light falls only on a small patch of wet mud, stones, and roadside grit.
• Traveler remains at frame edge or as a small silhouette, not seated or resting.

Character Handling

Back/side silhouette only if visible. Do not use face or portrait identity.

Composition / Scale

• Medium-wide to distant frame.
• Fire about 4%-7% of frame.
• Traveler about 1/10-1/6 at the edge, secondary.
• Keep negative space and dark road around the fire.

Light / Color / Texture

• Coal black and wet blue-gray night with local warm orange firelight.
• Mud, stones, and wet road texture must be tangible.
• Warmth is local, not a broad orange wash.

Forbidden Drift

No campsite, tent, chairs, cookware, social gathering, cozy lifestyle, large bonfire, heroic pause, fire worship, fantasy glow, labels, logos, UI, readable text.

Acceptance Checklist

• Fire illuminates a small mud/stone patch.
• Traveler remains peripheral.
• No camp props or group appear.
• D warmth is restrained.
• No review file is produced.
