850/// (`"no-inline-html"`); both forms match identically. Canonical IDs are
851/// the norm — every `Config` produced through a mutation boundary
852/// (`From<SourcedConfig> for Config`, LSP `apply_lsp_settings_*`, WASM
853/// `to_config_with_warnings`) is canonicalised by
854/// `Config::canonicalize_rule_lists`. The defensive canonicalisation here
855/// keeps `filter_rules` correct for programmatic callers that build a
856/// `GlobalConfig` without going through those boundaries.
