HRRR publishes f21-f48 at 3-hourly intervals in addition to the
hourly f01-f18 we already fetch. This extends the grid_tasks seed
from 19 rows (1 analysis + 18 forecast) to 29 rows (1 analysis +
18 hourly + 10 3-hourly), and bumps the UI forecast window
constant from 18h to 48h so the map timeline and path calculator
forecast chart automatically show the extended horizon.
No Rust logic changes needed — the pipeline is data-driven and
u8 forecast_hour already handles f48.
Rename all modules, functions, variables, routes, and UI text from
qso/qsos to contact/contacts. Database table stays as "qsos" to avoid
migration. Add /qsos -> /contacts redirects for old URLs.
Click anywhere on the propagation map to see a detailed popup with:
- Overall score and tier label with color
- Estimated range for the selected band (CW mode)
- All 9 scoring factors with visual bar charts, individual scores,
and weight percentages
- Grid point coordinates and data timestamp
Factors are displayed in weight order so users can immediately see
which atmospheric conditions are driving the prediction.
