SWC plugin fails on arrow functions with method calls in CSS interpolations: "Could not parse member expression"

[jantimon]

I ran into a bug when trying to use arrow functions with method calls inside a css template literal.
For example:

<Component css={css`animation-delay: ${() => (i * 0.05).toFixed(2)}s`} />

This throws: "Could not parse member expression" error during build

It looks like yak-swc tries to statically analyze the code to find constant value and can't handle calls like .toFixed() although these functions run at runtime.

The core of the issue seems to be in how member expressions are analyzed. The current logic tries to convert every member expression into a string path, but it doesn’t distinguish between safe, static accesses (like colors.primary) and method calls (like value.toFixed(2)), which shouldn’t be resolved at build time
