Each card is a single directory: - standalone HTML (no CDN, no external fonts) - bundled CSS + assets - print-ready PDF - JSON-LD metadata
No account. No platform. No external dependencies. The card itself is the product.
Goal: use LLMs to distill practical knowledge into small independent units — then make those units survive without the technology that created them.
"The best use of AI is not automation, but preservation — helping humans rebuild when machines are gone."

Identifier model:
Each card receives a 128-bit ULID. The bits are mapped to A/C/G/T, producing a 64-character DNA-like sequence.
The first 9 characters map to three craft “codon” words from a fixed vocabulary (e.g. klei·vuur·rots).
Properties: - Globally unique - Chronologically sortable - Bidirectionally decodable - No central registry
The DNA appears in the URL, footer, and print version.

Integrity:
Each build generates a SHA-256 manifest of all cards, signed with Ed25519. Verification happens client-side using the Web Crypto API (no server round-trip).

Build pipeline: Markdown + YAML → JSON Schema → Nunjucks → Puppeteer → signed manifest.
