Guidelines
Do
- Let one action lead each issue or review surface.
- Use neutral borders and quiet surfaces before adding color.
- Make human and agent ownership visible in the same activity context.
- Use motion only for handoff, progress, reveal, or state change.
Don't
- ×Do not copy the reference wordmark, protected copy, customer marks, or proprietary UI assets.
- ×Do not use gradients or color without a product meaning.
- ×Do not rely on color alone for status, errors, or selection.
- ×Do not add taxonomy filler or a dashboard-sized specimen.
Imagery
Use original CSS art, abstract geometry, and authored product frames. The two ordered screenshots are explicitly requested live reference media; do not use them inside component source or as decorative imagery.
Layout
Use one aligned content rail, generous section rhythm for marketing proof, compact product frames for workflow evidence, and a single-column mobile stack below 840px. Preserve readable gutters and let tables scroll rather than clip.
