name: no-vanity-metrics

# Blocks reintroduction of codebase-state numbers (crate counts, test
# counts, LOC, "N+ adapters", etc.) into READMEs and other Markdown
# surfaces. Those numbers drift on every code change and create
# permanent sync debt with the websites; the open-standards posture is
# "describe the shape, not the size." See CONTRIBUTING.md for the
# rationale and the opt-out marker.
