Where manual handoff breaks
A designer picks five colors, exports a PDF, and sends it to engineering. Engineering copies the hex values into CSS variables. A week later someone adjusts one shade in Figma but forgets to update the code. The pipeline is now out of sync, and nobody notices until a QA screenshot shows mismatched buttons. This is not a tooling problem. It is a format problem. The palette was never in a format that both sides could consume directly.
