Add Download Button for SVGs in Frontend #23

💾 Add Download Button for Haiku SVGs in Frontend

❓ What’s the Issue?

The frontend (frontend/src/App.jsx) currently lacks a button to download haiku SVGs, limiting users’ ability to save them locally.

🌍 Why Is This Important?

A Download SVG button will:

• 💡 Enhance HaikuReadme’s user experience by allowing users to save their custom haikus.
• 📤 Make it easier to share haikus in different formats, such as for social media or offline use.

🔧 Suggested Fix

• Add a “Download SVG” button in frontend/src/App.jsx, placed near the theme preview.
• Fetch the SVG from the API (e.g., /api?theme=dracula) and trigger the download.
• Use JavaScript (e.g., Blob, <a> element or your favourite approach) to save the SVG as theme-name.svg.

🧪 Additional Details

• Test with multiple themes like Nord and Catppuccin Mocha.
• Ensure the download button matches the existing UI styles (e.g., Dracula theme colors).
• The filename should include the selected theme, e.g., haiku-dracula.svg.
