- "My Location" button with text label (was just an icon)
- Two share buttons after results:
- "Copy Link" — fixed coordinates, exact result
- "Copy Link (use viewer's GPS)" — source=gps, dynamic per viewer

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.

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.
