The 1-hour valid_time filter inherited from /weather is wrong for HRDPS: the model publishes 4x/day with 3-4h publication latency and the chain step adds ~13 min on top, so the freshest data on disk is routinely 4-6h old. With the 1h cutoff in place, /weather-ca's timeline was empty whenever there wasn't an active chain step running, which left the JS hook with nothing to fetch. The sidebar already shows the selected valid_time prominently — users can see for themselves how stale the data is and don't need the page to hide it.
