The .deck format

A .deck file is a ZIP containing a deck.json manifest and a self-contained index.html. That's the whole contract. It plays offline, anywhere, in any conforming player.

• Open — CC0 public domain. No permission, no attribution, no royalties.
• Simple — one manifest, one HTML entry, optional thumbnail.
• Portable — self-contained; no server, no network, no companion files.

// deck.json
{ "schema": 1, "title": "Hello, Deck", "entry": "index.html" }
