Treatment (high_concept.md) — PASS

Criterion	Status	Notes
Prose format (not screenplay)	✅	Clean narrative prose, ~2,500 words
Word count 2,000–3,000	✅	Within range
Max 2 characters per scene	✅	Sarah + Mark throughout; Betty is ambient only
Clear emotional arc	✅	4-part musical tempo structure (Allegretto → Accelerando → Adagio → Coda) maps directly to pacing
Physical gesture vocabulary	✅	Rich and specific — napkin shredding, coffee stirring, hand-on-knuckles, coat unbuttoning
Single contained location	✅	Starlight Diner interior only — ideal for setting reference anchoring
Human-centric / event-compliant	✅	Zero overlap with banned themes
Dialogue-heavy	✅	Entire story is conversation-driven — perfect for our pilot mandate

Lip-sync assessment: The dialogue structure is technically ideal. Two speakers in a fixed booth, clear turn-taking with occasional overlap (the Accelerando section). Veo can handle this geometry — seated characters with consistent eyelines, minimal locomotion during speech.

Design Brief (design_brief.md) — PASS

Criterion	Status	Notes
Color palette defined	✅	Cherry red, chrome, golden amber, cyan/blue neon — highly encodable
Lighting specified	✅	Warm tungsten interior vs cool rainy exterior — strong contrast
Character visual anchors	✅	Distinct: Sarah (dark trench, emerald blouse, pulled-back hair) vs Mark (mustard corduroy, scruff)
Gesture vocabulary per character	✅	Specific, filmable, distinct per character
Camera distance map	✅	5-stage arc from wide → OTS → MCU → ECU → wide — directly usable
Prop anchors	✅	Manila envelope, ceramic mugs, cherry pie, rain-streaked window
Cinematic references	✅	Hopper’s “Nighthawks” + Wong Kar-wai palette — clear visual DNA

Extracted Tone Anchors (for prompt encoding)

These keywords go into every image and video generation prompt:

warm golden tungsten lighting, retro 1950s American diner, cherry red vinyl booths, chrome and Formica surfaces, rain-streaked window with cool blue neon glow, Edward Hopper “Nighthawks” aesthetic, intimate drama, melancholic warmth

Technical Notes for Step 2

1. Betty the waitress: Recommend keeping her off-screen or as a background blur. No full character treatment — she’d consume a reference image slot we need for Sarah/Mark, and the 2-character-per-shot rule means she can’t share a frame with both leads. In practice: show her hands pouring coffee, or a soft-focus figure moving in the background.

2. Setting reference strategy: One master diner reference image (the booth, the table, the window). This is reused in every shot. Budget per shot: 1 Sarah sheet + 1 Mark sheet + 1 diner setting = 3 references (exactly the Veo max).

3. Temporal continuity: The story spans maybe 45 minutes of in-world time. Visual cues for time passing: coffee level dropping, napkin becoming confetti, rain intensity changing (heavy → drizzle → stopped). These are encodable in prompts.

4. The 4-part tempo structure maps cleanly to 4 scenes for the Beat Sheet. Each part has a distinct emotional register and camera coverage style, which simplifies shot planning.
