Subject: [PATCH] fix: cap max hop distance at 300km, link to node detail not
 analytics
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 1000km filter was too generous for LoRa (record ~250km)
- Uhuru kwa watu 📡 ↔ Bay Area hops at 880km were obviously wrong
- Node links in leaderboard now go to #/nodes/:pk (detail) not /analytics
