-# Week 3 Quick Start Guide
-
-## ⚠️ IMPORTANT: Git Branching Workflow
-
-Before starting Week 3, create a new feature branch for this week's work:
-
-```bash
-# Create and switch to Week 3 branch
-git checkout -b week-3-cards-nav
-
-# Verify you're on the new branch
-git branch -v
-```
-
-**Why branching?**
-- Keeps each week's work isolated
-- Allows code review before merging to master
-- Easy to rollback if issues arise
-- Clean git history
-
-**At end of Week 3:**
-- Review all changes: `git diff master..week-3-cards-nav`
-- Test thoroughly in the branch
-- Merge back to master when ready: `git checkout master && git merge week-3-cards-nav`
-
-**For detailed workflow:**
-- See `GIT-WORKFLOW.md` for complete documentation
-- See `GIT-WORKFLOW-QUICK-REF.md` for common commands
-
-**Note:** Weeks 1-2 were completed on master (before branching policy). Week 3+ will follow weekly branching.

-## Key Principles
-
-✅ **Always use CSS variables** — Never hard-code colors  
-✅ **Build on existing components** — Buttons, badges already done  
-✅ **Mobile-first** — Start with smallest screen, expand up  
-✅ **Dark/light mode** — Test both modes  
-✅ **Accessibility** — Tab, focus, aria-labels  
-✅ **Smooth animations** — 200-300ms transitions, GPU acceleration  
-✅ **Keep it simple** — No bloat, Slackware philosophy  
-
-## Reference
-
-- `COLOR-REFERENCE.md` — All 30 CSS colors
-- `WEEK2-IMPLEMENTATION.md` — Button/badge patterns
-- `COMPONENT-TEST.md` — Testing checklist template
-
-## Still Stuck?
-
-Check existing partials:
-```bash
-ls themes/danix-xyz-hacker/layouts/partials/
-```
-
-Look for patterns in existing components:
-```bash
-grep "class=\"card" themes/danix-xyz-hacker/layouts/**/*.html
-grep "@apply" themes/danix-xyz-hacker/assets/css/main.css
-```
-
