How to optimize Figma vector exports & layout tokens for Core Web Vitals (INP/LCP) in UK enterprise builds?

Hi everyone,

When collaborating on enterprise web design and design-system implementations for UK clients, one recurring bottleneck our engineering team encounters is bridging Figma auto-layout tokens and complex vector assets into production code without degrading Core Web Vitals—specifically Interaction to Next Paint (INP), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS).

For engineering teams delivering high-performance UK web architecture and technical search optimization (such as our team at Beetle Dynamics SEO Services UK), unoptimized SVG exports with nested groups, deep frame hierarchies, and dynamic client-side vector re-renders frequently introduce DOM bloat and long tasks on the browser main thread.

I would love to learn from other design system engineers and front-end architects:

• What Dev Mode extensions or automated Figma export pipelines do you use to clean up vector paths, drop redundant layer wrappers, and minify inline SVGs before handoff?
• How do you structure tokenized auto-layout constraints so developers can map them directly to lightweight CSS Grid/Flexbox without excessive nesting?
• Are there specific plugin workflows you recommend to audit asset weight directly within Figma prior to developer handoff?

Looking forward to your insights and best practices!
