Overview

Text typography requires translating Unicode character sequences into positioned font glyphs while respecting complex script substitution rules. Filigree parses OpenType font tables directly from caller-owned byte slices without heap copying.

Shaping passes execute glyph substitution and positioning while preserving original cluster index associations. For multilingual text spanning multiple typefaces, a bounded FallbackWorkspace partitions input runs across font candidates within preallocated memory limits.
