No photos. Every picture is drawn in the same hand:
- Pen hatching at −32° fills each shape, with cut lines in strokes, a slight wobble and paper grain.
- Colors are gold plus the four inks: teal, brick, violet and amber.
- Subjects are simple objects that carry the idea: people, doors, ledgers, folders, stepping stones, a block on a waterline.
- No text inside a drawing. The caption or title carries the words.
- Sizes:
- essay header art (wide);
- section drawings (320×180, right of the text on wide screens);
- card drawings (84px wide, top-left of a card);
- band drawings (72px, beside each point).
Samples are in assets/Illustrations.
Charts
Essay charts are drawn: hatched bars and pen lines in the drawing inks, every number labeled directly, a source line, and the Signature at the bottom right. In a carousel or card, use the essay's own chart with the same numbers.
