Application background
Driftline system · Living · Contract 1.0.0
Design system
A portable method expressed as a precise ocean-research instrument.
Design principles
Calm enough to scan. Explicit enough to act.
- 01Make flow visible
Movement and blockage appear before secondary metrics.
- 02Explain the prompt
Every intervention shows its rule, evidence, age, and owner.
- 03Preserve human judgment
The system routes attention; people still decide, delegate, and support.
- 04Earn the density
Compact information stays readable, structured, and resilient.

Components and states
Native semantics · 44px targets
Actions
One primary commitment; quiet controls preserve hierarchy.
Status
Text, icon, and color carry the meaning together.
Selection
Pressed state is visible and exposed to assistive technology.
Input
Labels remain visible; supporting text describes the expected value.
Foundation 03
Snappy, purposeful motion
Visibility · continuity · feedback
Metrics resolve when they become visible.
Meters and values move as one state change.
