// Ferrous Solitaire — interactive browser game.
|

//
|
||
// Architecture:
|
||
// - `SolitaireGame` (Rust/WASM via solitaire_core) owns all rule logic.
|
||
// - This file owns the DOM renderer, drag-and-drop input, and the game loop.
|
||
// - Cards are persistent DOM elements keyed by `card.id`; positions are
|
||
// updated via `transform: translate(...)` so the browser can animate
|
||
// flights on the compositor thread.
|
||
//
|
||
// Pile name convention (mirrors solitaire_wasm::SolitaireGame::move_cards):
|
||
// "stock" | "waste" | "foundation-0".."foundation-3" | "tableau-0".."tableau-6"
