Key observations:

1. `is_plural` returns true for uncountables — "sheep" → true, "information" → true (words that can be plural ARE detected as plural)
2. Perfect round-trips — pluralize then singularize (and vice versa) always returns to original
3. Sub-millisecond latency — entire 63-call suite completes in <100ms total
4. No language detection — English only (non-English words pass through unmodified)
5. Based on the `pluralize` npm package by Blake Embrey — comprehensive English inflection rules
