How do I install Idukki on Custom / Headless?

Two ways. The native path uses the snippet + sdks + rest/graphql. Or paste the universal ~37 KB script snippet, which works on Custom / Headless (and any platform) today with no native install required.

Will the widget slow down my Custom / Headless store?

No. The runtime is a ~37 KB script that lazy-hydrates below the fold, so it has zero impact on theme load speed and Core Web Vitals.

Can I tag products from my Custom / Headless catalog?

Yes. 37 KB runtime, lazy-hydrates below the fold. Customers move from a customer photo or video to a tagged product and into the cart in a click.
