Mobile-first does not mean “mobile only.” It means you design for the smallest canvas first, then enhance for larger screens. That discipline prevents overcrowded navigation, tiny tap targets, and hero text that wraps awkwardly on phones.
For local and professional services, the first screen should answer three questions in seconds: who you are, what you offer, and how to contact you. Everything else supports those goals.
When performance budgets are part of the design conversation, you avoid heavy hero videos or oversized images that look fine on fiber but frustrate commuters on LTE.
