Deck of Cards
A single-developer keyless API for building card games: shuffle one or more standard 52-card decks (with or without jokers), draw cards, and split them into named piles, with each deck's state persisted server-side for two weeks of inactivity. Every response is JSON, including a URL to a PNG image for each card, and the plain-HTTP homepage now force-redirects to HTTPS.
Deck of Cards API simulates a standard deck of playing cards, letting you shuffle, draw, and split cards across piles for card-game backends without any local state management.

Gotchas & limits
- Save the `deck_id` from the response — every draw/shuffle/pile call after this needs it in the URL path
- Decks are discarded after two weeks of inactivity, so a stale `deck_id` can start returning errors
- `deck_count` defaults to 1 if omitted; use a higher value to simulate multi-deck shoes like blackjack
