lexicon_gate.rs

1//! Gate component for content that draws exercise words from the lexicon.
2//!
3//! On wasm the lexicon arrives via `/data/lexicon.json` (see
4//! [`crate::generator::ensure_lexicon`]); this gate holds its children back until
5//! the index is pinned so `Generator::new()` is always safe inside. Native builds
6//! resolve instantly, so tests and prerendering render children directly.
