• UPD River trend threshold lowered to 1cm (was 5cm) for more sensitive rising/falling detection
• UPD River colours: orange (rising), green (falling), blue (stable)
• DEL Removed Lightning overlay (Blitzortung) — not useful for situational awareness

• NEW ATCO Electric outages now render as boundary polygons (not just points) when area data is available

• FIX ATCO Electric scraper — now uses Firebase Anonymous Auth to authenticate before querying Firestore
• NEW Auth token cached for 50 minutes, auto-refreshes on 403, retries once on expiry

• NEW ATCO Electric power outage scraper — Firebase Firestore ActiveOutages collection
• NEW "ATCO Electric" checkbox in Power Outages submenu
• UPD Outage popups now show area name (e.g. "Fox Creek") for ATCO outages
• UPD Ticker hazard score includes combined FortisAlberta + ATCO customer totals

• FIX New alert flash extended to 5 seconds — map shapes pulse with thick stroke, sidebar entries flash severity colour
• FIX Flash now works while viewing alert details — 300ms render delay ensures Leaflet SVG elements exist
• UPD Map flash uses SVG stroke-width/fill-opacity animation instead of CSS transform (Leaflet SVG compatible)
