feat: create /features/design-system page with design system tools content

[devin-ai-integration]

Description

Creates a new /features/design-system page focused on design system management tools. This page follows the same pattern as other feature pages by cloning the page structure and updating shared components with design-system specific content.

Key Changes:

• ✅ New page at /features/design-system route with React import and proper setup
• ✅ Updated hero section with design system messaging ("Design System Tools for React")
• ✅ Replaced 3 benefit sections with design system focused content (Tailwind/Shadcn Editor, Centralized Globals, Template Import)
• ✅ Updated features intro section ("Complete Design System Management")
• ✅ Replaced features grid with 6 design system features (Asset Management, 1-Click Publish, Component Import, Gradient Picker, AI Animations, Layer Management)
• ✅ Updated CTA section text
• ✅ Added FEATURES_DESIGN_SYSTEM route constant

Type of Change

• New feature
• Bug fix
• Documentation update
• Release
• Refactor
• Other (please describe):

Testing

⚠️ CRITICAL: Shared Components Modified - This PR modifies shared components that are used by other feature pages. The following pages should be tested to ensure they still display correct content:

• /features - Original features page
• /features/ai - AI features page
• /features/builder - Builder features page
• /features/prototype - Prototype features page
• /features/design-system - New design system page

Testing Steps:

1. Navigate to each feature page URL
2. Verify hero section shows correct page-specific content
3. Check that benefits section shows appropriate content for each page
4. Confirm features grid displays the right feature set
5. Test responsive layout and styling consistency

Screenshots (if applicable)

Screenshots should be added after testing the deployed preview URL

Additional Notes

⚠️ Architectural Concern: This PR follows the pattern established by previous feature pages where shared components are modified with page-specific content. This approach may cause issues if multiple feature pages load simultaneously, as the last-loaded page's content could overwrite others.

Auto-formatting: Large portions of the diff contain auto-formatting changes from bun format that don't affect functionality but make the diff harder to review.

Content Review Needed: All content was provided by the user and should be reviewed for accuracy, tone, and alignment with product messaging.

The file has undergone extensive auto-formatting changes (e.g., additional parentheses and comma operator usage). While these changes appear cosmetic, they reduce readability and may risk subtle operator precedence issues. Consider separating formatting-only changes into a dedicated commit and double-check that the logic remains unchanged.

[ellipsis-dev]

Typographical error: There is an extra closing parenthesis at the end of the line. The assignment to g.parseCustomProperty should not be followed by an extra ')'.

[ellipsis-dev]

Typographical error: There is an extraneous opening parenthesis before b.addedNodes.forEach((e) => {. Please remove the extra '('.

[ellipsis-dev]

Typo: There's an extra closing parenthesis on this line. It currently reads "t.remove());" but it seems it should be "t.remove();". Please remove the extra ')' to resolve the issue.

[ellipsis-dev]

There's an extra opening parenthesis at the beginning of the assignment to l.assertNever (i.e. ((l.assertNever = t),). Please verify if the additional '(' is intentional or a typographical error.

[ellipsis-dev]

There's an extra opening parenthesis before this.spa = this.safeParseAsync. It looks like ((this.spa = this.safeParseAsync), may have an extra (. Please double-check if this is intended.

[ellipsis-dev]

Typographical Error: There is an extra closing parenthesis. The method call t.dirty()); should likely be t.dirty();.

[ellipsis-dev]

Typographical issue: There is an unnecessary opening parenthesis before "x(i, {". Consider removing the extra parenthesis for consistent syntax.

[ellipsis-dev]

Typographical issue: There is an extra opening parenthesis on this line. It should likely be corrected to a single parenthesis (i.e., change ((l.ZodString = 'ZodString'), to (l.ZodString = 'ZodString'),).

Let me try a different approach to understand the conflicts:

git branch -vv

# Check what remotes we have

I see the issue now! Let me examine this more carefully:

---

🏁 Script executed:

#!/bin/bash
# Let's see what commits are in each branch
echo "=== Commits in current branch (coderabbit_2747) ==="
git log --oneline coderabbit_2747 | head -10

git merge-base --is-ancestor origin/main coderabbit_2747 && echo "main is ancestor of coderabbit_2747" || echo "Not ancestor"

# Check the actual base commit of each branch

git log --oneline --graph --all | head -20

# Let's see the diff between the branches
echo "=== Showing file differences ==="
git diff --name-status origin/main...HEAD

Length of output: 699

---

Now I understand the issue! Let me check one more thing to confirm:

---

🏁 Script executed:

#!/bin/bash
# Let's look at the specific commits and their parents
echo "=== Current branch commit details ==="
git show --oneline -s coderabbit_2747
git log --oneline --parents coderabbit_2747 | head -5

echo "=== Main branch commit details ==="

# Let's see what the GitHub CLI says about the specific conflict
echo "=== GitHub PR merge status ==="
gh pr view 2747 --json title,mergeable,mergeStateStatus

Length of output: 814

---

Perfect! Now I have a clear picture. Let me check the actual differences that are causing conflicts:

---

🏁 Script executed:

#!/bin/bash
# Since there IS common history (1 commit in branch, 10 in main), let's find the merge base
echo "=== Finding merge base ==="
git merge-base coderabbit_2747 origin/main

# Let's see what files have been modified differently
echo "=== Files changed in this branch vs merge base ==="

git diff --name-status $MERGE_BASE..coderabbit_2747

echo "=== Files changed in main vs merge base ==="
git diff --name-status $MERGE_BASE..origin/main

echo "=== Files that conflict (changed in both branches) ==="
FILES_IN_BRANCH=$(git diff --name-only $MERGE_BASE..coderabbit_2747)
FILES_IN_MAIN=$(git diff --name-only $MERGE_BASE..origin/main)

echo "Files modified in this branch:"

# Find overlapping files

@itsNintu I can now see exactly what's causing the conflicts in PR #2747. Here's the breakdown:

🔍 Root Cause of Conflicts

Your PR is in a "CONFLICTING" state because the main branch has evolved significantly since this PR was created, and there are several overlapping changes:

📋 Key Conflicting Changes

1. Same Shared Components Modified: Both your branch and main have modified these shared components:

   • features-hero.tsx
   • benefits-section.tsx
   • features-grid-section.tsx
   • features-intro-section.tsx

2. Page Structure Conflicts: The main branch shows that your design-system/page.tsx was renamed/moved to ai/page.tsx, suggesting similar functionality was implemented for AI features instead.

3. 10 Commits Ahead: Main branch has moved forward with 10 commits that include:

   • New AI-specific components (ai-features-hero.tsx, ai-benefits-section.tsx, etc.)
   • Modifications to the same shared components your PR touches
   • New feedback system, various UI updates

🚨 The Core Problem

Your PR modifies shared components to show design-system content, but main has modified those same components to support AI features. This creates merge conflicts because Git can't automatically reconcile these competing changes.

✅ Resolution Options

1. Rebase and Resolve (Recommended):

   git rebase origin/main
   # Manually resolve conflicts in each shared component

2. Recreate the PR: Start fresh from current main and re-implement the design-system page

3. Alternative Architecture: Consider creating design-system-specific components instead of modifying shared ones (like main did with AI components)

Would you like me to help you with any of these resolution approaches?
