Participant questions

Framework assumptions?

Examples ship in React patterns, but concepts map to Vue and Svelte stores.

Hardware needs?

A laptop with Docker optional; throttling uses browser devtools primarily.

What is excluded?

We do not integrate live PSP endpoints—mock adapters only.

Recent reflections

Helpful race harness—minor nit: week two readings arrived late.
