SL-95 / Graphic Layer
The Doodle Contract
One pen, one physics, obeyed for the entire piece. Mixed styles are template soup.
The brief
Hand-drawn elements — arrows, underlines, scribbles — that obey one consistent style and one set of physical rules from beginning to end.
Why it's hard
The model varies the pen from mark to mark — one chalky, one neon, one glowing — and lets the marks float on a fixed screen plane instead of sticking to the world.
Design five rules before the first mark, then obey them to the frame. Anchor every mark to a real edge.

Starter prompt
Built with the CEMI MediaMax system for Google Veo 3.1. Prompts stay in English — that is the language these models take instructions in. Treat it as a starting point and start varying it.
A bicycle mechanic trues a wheel on a stand in a narrow repair shop, shot in the style of Michel Gondry with Ellen Kuras's 16mm handheld texture: the operator kneels, breathes, drifts a half-inch left and corrects. Dirty foreground: an oil-blackened chain hangs on a nail across the lower left, thrown soft by a 35mm at f/2 with visible focus breathing and warm edge softness. GRAPHIC CONTRACT, no exceptions: one white chalk-line pen, 3-frame draw-on, 4-frame fade, every mark anchored to a real edge (spoke, rim, wrench jaw), every mark obeying gravity, every mark wiped by the object that moves through it. Exactly three marks appear: a tension arrow along one spoke, an underline under the true section of rim, a wobble squiggle at the buckle. Same weight, same speed, same physics. Anodised alloy rim with rock rash, chalk dust on scarred plywood.

The lesson is not drawing, it is the contract: five rules written before the first mark and obeyed to the frame. Anchoring every mark to a real edge forces the overlay to inherit the shot's parallax and camera drift, which is what makes it read as designed rather than pasted. Three marks with identical draw-on timing beat fifteen marks in five styles.
The model will vary the pen — one mark chalky, one neon, one glowing — and let the marks float on a fixed screen plane instead of sticking to the spinning rim.
