// Document analytics pre-pass.
//
// Produces shared descriptive statistics about a parsed document — font,
// geometry, per-page distributions — that downstream rules consume as
// priors instead of recomputing locally.
//
// See `docs/P2/core/design-flows/2026-04-28-document-analytics-and-header-footer-classification.md`
// for the full design. Inspired by Postgres `pg_statistic`: descriptive
// primitives in core, threshold decisions in consumers.
//
// This module currently defines the type and trait shape only. The
// `observe()` and `finalize()` bodies are stubs; subsequent blocks
// (02 FontStats, 03 GeometryStats, 04 PageStats) fill them in.
