Series A · 04 sheets
Design systems
Systems built for products already in front of customers, measured by who reaches for them.
Three design systems since 2024 and one mobile component contribution. Each sheet covers the audit, the token architecture, the hard calls with the options that lost, and how the system stays alive with engineering.
Series B · Product designThe system, measured
Every colour is a semantic role, not a value. The build measures each role against each surface in both modes and refuses to emit a stylesheet below the minimum. The red you see moved one stop lighter because it failed at 3.58:1.
