illustration-halftone-line
Draws hand-authored SVG spot illustrations in a halftone line style for design and coding scenes. Identifying traits are a confident black line with a slight hand wobble and contours left open, grey tones made only of fine halftone dots clipped to shapes, a few solid black masses (hair, leaves, a bag, a black tee), warm off-white paper and no colour at all. Covers the two-ink palette, line weights, the open-contour and stipple techniques, a seeded compiler that turns tone tags into dot fills, rubbery long-limbed characters and expressive hands, doodles, floor pools and a render-and-critique loop. Use when someone asks for halftone, stipple, dotted, risograph-like, newsprint, black-and-white, monochrome line, editorial line or zine-style illustrations, or for empty states, onboarding, 404 pages, blog headers, feature spots and marketing cards in that look.

# Illustration: Halftone line
An editorial black-and-white style: one black ink on warm paper, figures drawn with a confident, slightly wobbly line that stops short instead of closing, and every grey made of printed-looking dots. It suits calm, human product moments: collaboration, reviews, commutes, focus time.
Boundary: for a single continuous line with off-register colour patches use `illustration-one-line`; for thick brush outlines with a second flat ink use `illustration-two-colour-brush`; for thin indigo interiors with sparse colour accents use `illustration-line-interior`. If the brief wants any colour, this is the wrong skill.
Extracted from a set of 42 original design-and-coding cards in 14 styles; the three cards in `examples/` are this style's shipped cards.
## The look in one sentence
Black line and black dots on warm paper, nothing else: every grey is a field of jittered halftone dots whose size tracks the tone, and the line around it is left open.
