The mobile default
Mobile-first is not a checkbox—it is a constraint that improves clarity for *every* viewport. Tight information hierarchy, thumb-friendly hit targets, and fast first paint are baseline expectations.
What Cocodly nudges you toward
- Stacked, legible sections on narrow widths
- No hover-only affordances; parallel paths for touch
- Image discipline: right sizes, no layout thrash
PWAs: optional superpower
When you need home-screen presence or offline-tolerant flows, a PWA strategy can make sense. Cocodly’s generated sites are a strong starting point for semantic structure and performance budgets you can build on.
Build for the **3G mindset** first; Wi‑Fi polish comes second.
Measure on real devices
Use field data, not just Lighthouse in ideal conditions. Cocodly helps you get to a clean structure early so tuning Core Web Vitals is about refinement, not rescue work.
