Building 1:1 from Figma

Figma is the source. The bar is 1:1. One pixel off is a failed build. The only way to hit that bar reliably is to round-trip. You do not get there by building once and hoping — you get there by measuring your implementation against the file, over and over, until nothing differs.

Before you write any code

• figma-import must have run. You build from its token-binding table and spacing map — not from an image, and not from a partial pull. If the context isn't fully captured, go back and capture it. A lazy pull guarantees a failed 1:1.
• Build from tokens, verify against the screenshot. The numbers you type come from the extracted variables. The screenshot only ever confirms them.

The round-trip loop

This is the skill. Repeat until the measured diff is zero.
