The answer
Create dots for each step. For each dot: add 'completed' class if index < currentStep, 'active' class if index === currentStep. For connecting lines: add 'completed' class if index < currentStep. Update on every step change.

Two options: linear (a progress bar with width = ((currentStep + 1) / steps.length) * 100) or stepped (dots with completed/active states connected by lines). Update on every step change. Completed steps are green, active is blue.
Dots: circular (border-radius: 50%), fixed size, centered text. Lines: flex: 1, thin height (2px). Completed: green background. Active: blue background. Default: gray background. Use display: flex on the container with align-items: center.
((currentStep + 1) / steps.length) * 100. For example, step 2 of 4: ((2 + 1) / 4) * 100 = 75%. Wait, step 2 of 4 (0-indexed): ((1 + 1) / 4) * 100 = 50%. Use currentStep + 1 because steps are 0-indexed.
