Root cause (diagnosed live, not the hypothesised JS throw): filterCountries runs fine and correctly populates the list, but reveals it with `list.style.display=''`. The .geo-country-list CSS default is `display:none` (style.css), so clearing the inline style falls back to none and the populated list never shows — no console error, just an invisible dropdown. Latent since the geo feature's first commit. Fix: reveal with 'block'. Verified live (typing "Német" now lists Németország). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
