Arc 7 Catch-Up: Building NFTs from First Principles

Arc 7 of 100 Days of Solana built NFTs from first principles by stripping the model back to token mechanics. An NFT is a token with supply locked at one, zero decimals, mint authority disabled, and metadata attached. This shows that NFTs are not a separate world but built from the same token primitives. Web2 developers should notice this shift as it's not magic, but a token with specific properties.
