/**
 * @file settingsSearch — the Settings page's search: `SETTINGS_INDEX` names the

 * prefix beats substring: section title 900/850/800, entry title 700/650/600,
 * description 500/450/400, keywords 300/250/200; a section scores its best hit.
 * `rankSettingsEntries` ranks the rows themselves, for the result list that
 * deep-links a row's sub-tab and anchor.
