Consistency is one of the cheapest ways to make a website feel professional.
Start with tokens
Define colours, type sizes and spacing once, then reuse them everywhere. Changing the brand later becomes a one-file edit.
Build components, not pages
Buttons, cards, headers and form fields should be reusable pieces. New pages are then assembled rather than designed from scratch.
Document the rules
Even a short note on when to use each component prevents drift as more people touch the project.
