Typography
Heading scale and spacing
Body text carries thought at a calm, readable rhythm. Monospaced labels orient, classify, and timestamp.
Visual grammar
Space
Use tighter intervals within a group and broader intervals between groups; repeat intervals consistently.
Color
PAPERINKGRAPHITESIGNAL
Use paper, ink, and graphite for structure; reserve signal red for state, direction, or urgency.
Rules + boundaries
Hairlines group information. Strong rules indicate a shift in mode, ownership, or sequence.
Composition
The grid establishes alignment; departures should clarify emphasis, sequence, transition, or argument. When ornament competes with the structure, prioritize clarity over ornamentation.
