+
+Testing the new GitHub-like syntax highlighting across different languages to ensure consistency.
+
+## Bash Example
+
+```bash
+#!/bin/bash
+echo "Testing bash syntax highlighting"
+for file in *.txt; do
+    if [[ -f "$file" ]]; then
+        echo "Processing: $file"
+        wc -l "$file"
+    fi
+done
+```
+
+## PowerShell Example
+
+```powershell
+Write-Host "Testing PowerShell syntax highlighting"
+Get-ChildItem -Path "*.txt" | ForEach-Object {
+    if (Test-Path $_.FullName) {
+        Write-Output "Processing: $($_.Name)"
+        (Get-Content $_.FullName).Count
+    }
+}
+```
+
+## JSON Configuration
+
+```json
+{
+  "name": "test-project",
+  "version": "1.0.0",
+  "scripts": {
+    "build": "webpack --mode production",
+    "test": "jest --coverage"
+  },
+  "dependencies": {
+    "express": "^4.18.0",
+    "lodash": "^4.17.21"
+  }
+}
+```
+
+## YAML Configuration
+
+```yaml
+name: Build and Test
+on:
+  push:
+    branches: [main, develop]
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - name: Setup Node.js
+        uses: actions/setup-node@v3
+        with:
+          node-version: '18'
+```
+
+This should demonstrate consistent highlighting across different code languages.
