Headless means your storefront talks to commerce APIs instead of rendering everything from a monolithic template. Flexibility rises; integration work does too.
It shines when you need bespoke UX, multiple frontends, or aggressive performance tuning on the presentation layer.
It hurts when your team lacks API maturity or when marketing wants turnkey theme editing without developers.
Start with clear ownership: who owns product data, promotions, and caching? Ambiguity becomes slow releases.
