Loam: MTB Trail Conditions

This update brings smarter alerts and a more polished trail view. • Smarter ride alerts. When several of your trails turn prime at once, you now get one clean notification instead of a stack of them, with quiet overnight hours and a daily limit so you are not pinged at 2am. • Fixed false "prime" alerts. Overnight dew and fog could briefly make a dry trail read as freshly dry the next morning and fire a bogus alert. Now a notification means a real change. • Condition history. Each trail shows its recent condition trend, so you can see how the last couple of weeks have gone at a glance. • Cleaner trail list. Removed duplicate networks so search results are tidier. • Stability and reliability improvements under the hood.
