//! Per-glyph metrics of a compiled font atlas: where a glyph sits in the atlas
//! texture and how the pen moves across it. Shared by the build-time rasteriser
//! that writes the payload, the decoder that reads it back, and the text layout
//! that turns it into quads, none of which owns the layout.

/// Per-glyph metrics stored in the compiled payload.
