- Build /data/domains.duckdb on first run (tld+parts columns + ART index)
→ TLD filter goes from ~60s full scan to <100ms index lookup
→ System still works (slower) while index builds in background
- New /api/domains params: alpha_only, no_sld, keyword
→ alpha_only: domains with only letters (no hyphens/numbers)
→ no_sld: parts=2, excludes com.es / net.es patterns
→ keyword: LIKE '%term%' niche search
- /api/domains and /api/enriched now return total count for pagination
- Pagination: shows total matches, page X of Y, Next disabled at last page
- Enrich button: toast notifications instead of alert(), error handling
- Select all on page button, clear selection button
- Stats/TLD breakdown cached after first load (no repeat full scan)
- Header shows index build status (building → ready)
