Graham McIntire e3d430f8c4 feat(weather): add duct cutoff band map layer ... Show on /weather where the detected duct geometry traps each microwave band. Overview mode bins cells by their lowest trapped frequency (Bean & Dutton cutoff); band-picker mode masks cells whose duct doesn't reach the selected band. Cutoff is pre-computed per cell in both writers (Elixir derive + Rust derive_row reads best_duct_freq_ghz from CellValues), persisted to ScalarFile, and shipped to the JS hook via the existing binary cell pack. Also cleans up six pre-existing length/1 credo warnings in unrelated test files.		2026-05-15 19:51:24 -05:00
