Move the /weather render path off raw HRRR profile decoding + per-cell SoundingParams + WeatherLayers derivation. The dominant cost was re-deriving the same scalar fields on every viewport pan and timeline scrub. Server side: - New Microwaveprop.Weather.ScalarFile persists pre-derived scalar rows on NFS, bucketed into 5°×5° chunk files under <base>/weather_scalars/<iso>/<lat_band>_<lon_band>.etf.gz. Viewport reads only decode the chunks that overlap the requested bounds; point-detail clicks read exactly one chunk. - weather_grid_at/2 and weather_point_detail/3 prefer ScalarFile; ProfilesFile is now the cold-start fallback only. - warm_grid_cache_and_broadcast/1 and warm_grid_cache_from_latest_profile/0 also persist the scalar artifact, and the cold-derive path kicks off a per-valid_time-locked async materialization so the next reader gets the cheap path. - NotifyListener.handle_propagation_ready/1 fires Weather.materialize_scalar_file/1 in a detached Task on the Rust pipeline's NOTIFY propagation_ready, so steady-state forecast hours arrive with their scalar artifact already on disk. - available_weather_valid_times/0 unions ScalarFile + ProfilesFile so the timeline survives an aggressive retention sweep on either side. Browser side (finding #8): - Mount the legend Leaflet control once and patch its inner content on layer changes instead of remove + re-add on every renderLayer. - renderTimeline now keys off the rendered button set: selection-only updates take an applyTimelineSelection patch path that restyles existing buttons in place. Full innerHTML rebuild only fires when timelineData itself changes. Also fixes a credo nesting-depth flag in tile_renderer.ex by extracting interpolate_pair/2 from the inner anonymous function.
