Challenge: Architecting an Enterprise Contribution Flow

Consider a high-growth fintech with 150 engineers across 12 product squads. The checkout squad needs a customized 'CountdownTimer' component for flash deals within two weeks.

Applying our governance principles:

• Immediate Squad Need: The squad builds the component locally in their checkout feature branch, strictly using design system tokens (color-bg-warning-subtle, space-12, font-mono-tabular).
• RFC Evaluation: The squad submits an RFC proposing the component for @system/lab. During review, the marketing and travel squads confirm they also need flash-sale timers.
• Promotion: The checkout squad authors the component in the Lab package with visual regression tests and accessibility documentation, where it is approved and merged.
