[UI/UX Design] Design branded loading states with shimmer and progress hierarchy

[thlpkee20-wq]

Description

Current loading states vary between spinners, dots, and ad-hoc skeletons. Define a coherent set of branded loading states: button spinner, inline progress, page-level loader, and section skeleton, all using one shimmer token.

Requirements and context

• Must be accessible (WCAG 2.1 AA), responsive, and documented in the design system
• Should be consistent with existing patterns and easy to review
• Relevant code: src/components/Button.tsx
• Shimmer must pause under prefers-reduced-motion; spinners must include aria-label

Suggested execution

• Fork the repo and create a branch
• git checkout -b uiux/branded-loading-states
• Implement changes
  • Define the shimmer token and four loading variants
  • Document when to use each (latency thresholds)
  • Add reduced-motion fallback
• Validate accessibility and responsive assumptions

Test and commit

• Run checks
  • npm run lint and component/visual tests
• Cover edge cases
  • Sub-200ms (no spinner), 200ms-2s, >2s with cancel, mobile, RTL
• Include screenshots/before-after and accessibility (axe) notes

Example commit message

design: branded loading states with shimmer token

Guidelines

• Minimum 95 percent test coverage
• Clear documentation
• Timeframe: 96 hours
