[egdev6]

Summary

Completes the Link atom review and validation.

Closes #132

Type of change

• 🧩 New component
• 🐛 Bug fix
• 🎨 Design tokens
• ♿ Accessibility
• 🏗️ Infrastructure
• 📚 Documentation

Component checklist (skip if not applicable)

• Follows the 5-file structure (types.ts, use*.ts, Component.tsx, index.ts, *.stories.tsx)
• CVA variants defined in types.ts, not inline
• No hardcoded colors — uses tokens from theme.css
• No any types — TypeScript strict
• ARIA attributes present and correct
• Keyboard navigable (Tab, Enter, Escape where applicable)
• Dark mode works correctly
• Storybook stories cover: default, variants, states (hover, focus, disabled)
• Tests added or updated

How to test

1. pnpm test -- src/components/atoms/link/Link.test.tsx
2. pnpm exec tsc --noEmit
3. pnpm run build
4. pnpm run storybook-build
5. Navigate to Atoms/Link and verify inline, CTA, shadow, size, disabled, target, and action-mode stories.

Screenshots / recordings (if applicable)

Not included.

Notes for reviewer

• regular is now a true inline link; button maps to primary CTA; outlined maps to secondary CTA.
• shadow={false} disables CTA glow while preserving focus ring accessibility.
• src/styles/theme.css adds Tailwind shadow utility aliases for existing --glow-btn-* tokens so shadow-glow-btn-* classes generate correctly.
• Fresh pre-PR review passed. Review workload note: the diff is bounded to Link plus theme aliases, but it is over 400 changed lines due to story/test coverage.
