# Hardware illustration brief

The current production asset is `public/assets/prototype-rough-v1.png`, generated with the built-in image-generation tool. The reusable brief below describes its visual language; it is not a manufacturing specification.

```text
Use case: stylized-concept.
Asset type: editorial hardware illustration for an open physical-robot build journal.
Subject: a DIY CoreXY robot with a rectangular extrusion frame, linear rails, belts, two stepper motors, a movable capacitive stylus, a camera overlooking the phone, and a clearly recognizable iPhone 14 held face-up in the center. The phone has a black bezel, top notch, rounded corners, sketched app icons and a bottom home indicator. Keep it prominent and unobstructed.
Style: raw black ink, graphite construction lines, rough charcoal crosshatching, red grease-pencil accents, imperfect doubled outlines, subtle measurement ticks and restrained gray marker shadows.
Composition: landscape 3:2, elevated three-quarter perspective, complete mechanism in frame, readable silhouette, warm off-white paper and generous surrounding space.
Palette: studio red #ce1019, charcoal #141414, warm paper #f3eee5, gray/chrome details.
Constraints: conceptual workshop sketch, not a photograph of a finished machine or a glossy CAD render. No characters, written labels, logos, watermarks or fake paragraphs. Add real typography in HTML.
