rustfmt.toml sets group_imports, imports_granularity and imports_layout, which are nightly-only; agents formatted with stable rustfmt, which ignored them. This is a formatting-only pass with `cargo +nightly fmt`. Test Plan: - cargo clippy --workspace --all-targets -- -D warnings - cargo test --workspace

//! CodepointMap is a map of codepoints to a discovery descriptor of a font
|
|
//! to use for that codepoint. If the descriptor doesn't return any matching
|
|
//! font, the codepoint is rendered using the default font.
|
|
//! Port of `font/CodepointMap.zig`.
|
|
|
|
//!
|
|
//! The canonical definition lives in `ghostty-config` (the `font-codepoint-map`
|
|
//! option parses straight into it); it is re-exported here.
