The foundation: plan the structure, set up the project, build the layout, create page component stubs, build reusable primitives, add loading and error states as stubs, and connect to real data as the backend is ready.
Because the layout is the shell every page uses. Building it first means every page renders inside a consistent shell from the start, with the persistent UI like header and sidebar in one place.
Because Button, Card, Input, and Avatar are used everywhere. Building them once with consistent styling means your UI stays consistent and you do not write the same styling on every page.
