Hurricane / tropical storm fixes
- NHC intensity is in knots: show real mph (80 kt = 92 mph) instead of mislabelled 'mph'
- Real Saffir-Simpson category from wind (was always cat 1); subtropical, post-tropical and
potential-cyclone types no longer shown as 'depression'; each storm shows movement
(direction + mph, previously a non-existent field), distance from you, update time, advisory link
- Forecast track points coloured by their own forecast strength (not the current class)
- Map click handlers registered once (popups stacked on every refresh); overlays wait for the
map to settle instead of silently not drawing while tiles load; stale renders superseded
- Subtropical/tropical advice added to alert guidance; escaped storm names
Alert cards (active alerts only)
- What it's for, area, window, time remaining, plain-language meaning, what to do, and a
Full details expander (headline, text, instructions, severity/urgency/certainty, issuer)
- No longer drops alerts beyond 6 per severity group; expired alerts are filtered out
- Shared plain-language alert glossary (alert-info.js, 64 products incl. tropical and surge)
now used by both the app and the dashboard history
