/**
 * Stopword list for the online dnsNotFound Search CTA keyword extractor
 * (bug 2057648). This is a deliberate fork of the shared ENGLISH_STOP_WORDS
 * (chrome://global/content/ml/NLPUtils.sys.mjs), owned by URLKeywordAnalyzer,
 * for two reasons:
 *
 *   1. Decoupling. The shared list is also consumed by Smart Tab Grouping; a
 *      retune there would otherwise silently shift the CTA's derived queries,
 *      and our content-free telemetry could not detect the regression.
 *   2. Curation. For URL -> query recovery the list is tuned for path segments
 *      rather than prose: it keeps content words the general list
 *      over-aggressively drops, and folds in URL-structure words that only
 *      ever describe page plumbing.
 *
 * The curated list was settled in bug 2055619 comment 3. Words present in the
 * shared list but intentionally OMITTED here, so they survive into a query:
 * "fire", "interest", "name", "part", "system", and the spelled-out numbers
 * ("one" through "twelve", "twenty", "fifty", "hundred", ...).
