The Dagrun brand, in one scroll.

Dagrun is poly LLM + agentic local task orchestrator. The mark is a solid half-disc (the “planner”), a stem (the routing line), and the signal dot (the local, active node). Identity is paper + ink + one accent — nothing else.
01 · Mark

Construction

Drawn on a 64-unit grid. Half-disc: 28r arc centered at (32, 32). Stem: 6×22 rect sitting below the flat edge. Signal dot: 6r circle flush with the stem’s base. Keep the proportions exact — the dot must visually sit on a ground line, not float.

Three colors do all the work.

Paper, ink, signal — and the extended neutral ramp for surfaces. If your screen has four accent colors you’re off-brand. See /tokens for the full CSS-var and SwiftUI Color extension set.

04 · Typography

Three families. One voice.

Inter Tight for display & UI chrome. Inter for body copy. JetBrains Mono for code, timestamps, and metadata eyebrows. On Mac, bundle the fonts into the app via ATSApplicationFontsPath. Fall back to SF Pro only when the custom font fails to load.
