Bookmarking /path?source=gps&destination=K5TR&band=10000 will use
the viewer's device GPS to resolve the source location on load.
The LocateMe hook handles both button clicks and server-pushed
request_gps events. Once coords are resolved, the URL is updated
with actual lat,lon and calculation runs automatically.

- 18-hour propagation forecast bar chart from grid scores at path midpoint
Shows best/worst score and time, color-coded bars
- URL query params: all form fields reflected in URL, auto-calculates
when source+destination present. Bookmarkable/shareable links.
- phx-change on form updates assigns in real-time as user types
- Removed LiveStash in favor of URL-based state persistence

- TX/RX height in feet (converted to meters for terrain analysis)
- TX power in dBm with mW equivalent display
- TX gain and RX gain (dBi) inputs
- Power budget: TX power + TX gain - feed loss = EIRP - path loss
+ RX gain = RX power vs CW sensitivity = margin
- Loss budget: FSPL + gaseous (O2+H2O) + diffraction + rain
with per-km gas rate detail
- GPS "Locate Me" button using browser geolocation API
- Lat,lon coordinate pairs accepted as input
- Weather displayed in F with C below
- LiveStash preserves form inputs across page reloads
- Terrain cross-section with beam line and Fresnel zone

LiveView page for analyzing microwave propagation between two points.
Features:
- Source/destination input: callsign (via gridmap.org API) or Maidenhead grid
- Band selector for all 8 microwave bands (10-241 GHz)
- Leaflet map showing path line (reuses ContactMap hook)
- Terrain elevation cross-section (reuses ElevationProfile hook)
- Link summary: distance, bearing, terrain verdict
- Loss budget: FSPL + O2 + H2O + rain + diffraction
- Propagation score with 10-factor breakdown
- Current atmospheric conditions from path-integrated HRRR
New CallsignClient for gridmap.org location lookup.
Navigation links added to main navbar and map control panel.

Add sections for all three new data sources in Meteorological
Foundations: path-integrated scoring strategy, ERA5 reanalysis
for pre-2014 contacts, RTMA 15-minute surface analysis. Update
calibration dataset summary with ERA5/RAOB/RTMA coverage.

Enqueues ERA5 fetch jobs for contacts where HRRR is unavailable.
Deduplicates by rounded grid point and hour, skips existing profiles.

Contact scoring now uses all HRRR profiles along the path instead of
just pos1. Aggregation strategy:
- Best along path for beneficial factors (refractivity, pressure)
- Worst along path for harmful factors (rain, wind)
- Average for neutral factors (temp, dewpoint, PWAT, BL depth)
Scorer.path_integrated_conditions/2 merges multiple profiles into a
single conditions map. Falls back gracefully to single-profile scoring
when only one profile is available.

Scorer.path_integrated_conditions/2 merges multiple profiles into a
single conditions map. Falls back gracefully to single-profile scoring
when only one profile is available.
Uses Repo, Scorer, BandConfig, Weather directly instead of raw SQL.
Scores all historical contacts with the real composite_score/2 and
includes factor heatmaps and weight sensitivity analysis.
Connects to local dev DB to analyze contacts, HRRR conditions,
terrain impact, commercial link correlation, and score sensitivity.
Ready for use once prod data is imported locally.
