[PHYSIOLOGICAL & ACTION DETAILS]
- Sweat beads: Ultra-realistic individual sweat droplets visible on forehead, neck, and upper chest - size varies from pinhead to 2mm, mixed sharp focus (foreground) + slight blur (midground). Do NOT overdo to avoid looking oily.
- Dynamic motion blur: Moving limbs (legs swinging, arms pumping) have natural directional motion blur at 25-30% intensity, static body core (torso, face) MUST remain pin-sharp. Face always crisp for recognition.
- Skin micro-texture: Pores visible on nose and cheeks, slight skin flush (rosy cheek tint) from exertion, NOT airbrushed doll-like perfection.
- Facial expression: Jaw slightly clenched, eyes focused sharply 20 meters into distance (not looking at camera), eyebrow muscles minimally tensed. Reserved determined toughness, NO exaggerated screaming.

[LIGHTING SIGNATURE]
- Golden Hour Magic: Always shoot at 35 minutes before sunset. Sun angle exactly 8-12 degrees above horizon line.
- Color temperature: 5200K warm gold base with subtle amber #FF9933 rim light tint on backlit hair and shoulders.
- Lens flare: Anamorphic horizontal oval lens flare streaks at 15% opacity, cyan-blue tint, originating from sun position behind subject's shoulder line.
- Shadow: Long dramatic shadows stretching 3x subject height, 40% opacity soft edges.

[SHOE & GEAR RENDERING RULES]
- Zephyr WindWing 3 carbon plate shoe: ALWAYS render left shoe lateral side view as hero angle. Carbon plate visible through translucent midsole edge as thin black line. Shoe upper knitted texture with 3D woven pattern sharp.
- Logo placement: Zephyr logo on chest of shirt + shoe side + shorts leg - size ratio strictly 1:15 of clothing panel. Logo color: Reflective silver that catches golden rim light.
- Bib number (for running only): White rectangular bib with black text. Runner number 7 digits: "Z-2026-林". Safety pins visible at 4 corners.

Style: Nike Breaking2 campaign meets Red Bull Illume photography. Cinematic. 8K RAW quality. Hasselblad X2D 100C look. Do NOT look like CGI. Do NOT look fake. Generate 4 tone validation test crops (sweat close-up, shoe detail, face expression, shadow).

MULTI-FORMAT ADAPTATION ENGINE - same subject/scene, different canvas ratios WITHOUT changing person/action/lighting consistency:

CONSISTENCY NON-NEGOTIABLE RULES (fail if any violated):
1. Subject facial features IDENTICAL across all crops: eye shape, nose bridge angle, jaw contour, sweat pattern location (left forehead 3 beads, chin 1 falling droplet MUST match original)
2. Subject pose IDENTICAL: limb angles, torso rotation, hand positions do NOT shift by more than 5%
3. Lighting IDENTICAL: golden hour sun angle 10 degrees, anamorphic flare streak position, shadow length/direction all match pixel-level
4. Gear IDENTICAL: shoe lacing pattern, logo placements, watch face data numbers all exactly same

RATIO ADAPTATION INSTRUCTIONS - take Shot A (marathon group hero horizontal original) and adapt:

[FORMAT 1 - STOREFRONT LIGHTBOX 超横版 (4:1 ratio, 4800x1200px)]
- Extend canvas LEFT and RIGHT equally. DO NOT CROP OR ZOOM original subject group.
- Left extension: Continue Shanghai Bund riverside promenade, add more blurred spectators behind barrier + banner boards with sponsor logos (Zephyr large, official sports drink small).
- Right extension: Continue finish straight, add pace car blurred distant, timing clock gantry showing "2:08:42" readable, medical tent visible far right.
- Keep original 5-runner pack dead-center of 4:1 canvas. Vertical dimension preserved exactly.

[FORMAT 2 - TMALL DETAIL PAGE FIRST SCREEN 竖版 (9:16 ratio, 1080x1920px)]
- Subject (Lin only, remove other 4 runners). Place Lin at 40% from top of frame (golden ratio upper for portrait).
- Extend canvas UPWARDS: Dramatic sky above Lujiazui - dramatic altocumulus cloud streaks warm golden. 40% of canvas = sky + skyline.
- Extend canvas DOWNWARDS: Legs full length + ground shadow extended. Add Zephyr shoe box shot floating at bottom 20% on clean white overlay card for product association.
- Keep Lin's original running pose 100% identical, just remove competitors digitally and center him in vertical composition.

[FORMAT 3 - XIAOHONGSHU SOCIAL SQUARE (1:1 ratio, 1080x1080px)]
- Tighter crop upper-body + head only, Lin only.
- Original face pixel-identical. Frame Lin face at rule of thirds upper-left intersection.
