/**
 * Style Targets — machine-readable quantitative prose targets.
 *
 * A project may ship a `style-targets.yml` at its root declaring the numeric
 * style targets that the deterministic analyzers compare against (sentence
 * length, modifier density, passive voice %, punctuation cadence, etc.). This
 * is the structured counterpart to the prose STYLE_GUIDE.md files: the .md
 * guides hold qualitative voice guidance for the LLM editors, while this file
 * holds the numbers the deterministic tools can actually measure against.
 *
 * Missing file → sensible general-fiction defaults are used. Any field omitted
 * from the file falls back to its default; a field set to `null` disables that
 * check entirely.
