From 1ef1da7c0d0bbe3fc21af3e5a833c94a983fd84d Mon Sep 17 00:00:00 2001 From: Stan Grams Date: Sun, 1 Mar 2026 17:50:39 +0100 Subject: [PATCH] [feat](trx-frontend): show animated radio path on APRS station click Draw a blue dashed polyline from the receiver to the clicked APRS station on popup open; remove it on popup close. CSS stroke-dashoffset animation creates a traveling-dash effect suggesting signal propagation.
