Add technical breakdown to svg nft challenge

[rin-st]

Add a section after the "Quest Journal", showcasing the most interesting technical points of the Challenge. Like we had in the Multisig-break-down

From #184 (review)

Tried to write Quick break down for svg nft with cursor and ended with this

Breakdown

👇🏼 Quick Break-Down 🎨

Smart contract generates dynamic SVG NFTs entirely on-chain using deterministic randomness, dynamic pricing, and real-time SVG generation.

🔄 Minting Flow:

1. User calls mintItem() with ETH payment that meets current price
2. Contract generates unique traits (color, chubbiness, mouth length) and auto-increases price for next mint
3. Payment forwarded to recipient, NFT minted to user

🎨 SVG Generation:

• tokenURI() creates Base64-encoded JSON metadata with embedded SVG image
• renderTokenById() builds dynamic SVG art with eyes, head, and mouth positioned using trait-driven calculations

🚀 Technical Highlights:

• 🔒 Deterministic randomness: generates predictable yet unique traits for each mint
• 💎 Scarcity economics: price grows exponentially with each mint
• 🔗 Zero dependencies: no IPFS, no external APIs - pure on-chain storage
• ⚡ Gas efficient: SVG built with string concatenation, Base64 encoding in-contract

But it's very similar to already existing to challenge description, except some additional details

Description

🎨 Creating on-chain SVG NFTs is an exciting way to leverage the power of smart contracts for generating unique digital art. This challenge will have you build a contract that generates dynamic SVG images directly on the blockchain. Users will be able to mint their own unique NFTs with customizable SVG graphics and metadata.

🔗 Your contract will handle the creation and storage of the SVG code, ensuring each minted NFT is unique and stored entirely on-chain. This approach keeps the artwork decentralized and immutable.

💎 The objective is to develop an app that allows users to mint their own dynamic SVG NFTs. Customize your SVG generation logic and make the minting process interactive and engaging.

🚀 Once your project is live, share the minting URL so others can see and mint their unique SVG NFTs!

🌟 Use Loogies NFT as an example to guide your project. This will provide a solid foundation and inspiration for creating your own dynamic SVG NFTs.

So I'm thinking do we need quick breakdown at all? I'm 60% No / 40% yes
What do you think @Pabl0cks @damianmarti

Update: Changing title to "Quick Loogies NFT Breakdown" makes it better. Now I'm 40% No / 60% yes 🙂 . Creating PR so you could see how readme looks with the update. We could close it later if needed
