Retrieve NWS mountain/recreational zone forecast text products (REC, FZL freezing levels) for a ski area, distinct from generic gridpoint forecasts

Steps
Identify the NWS Weather Forecast Office (WFO) covering the resort (e.g., SEW for Washington Cascades)
Fetch the office's dedicated mountain-forecast landing page (e.g., weather.gov/sew/Mountainforecast) to find linked recreational forecast products
Retrieve the recreational forecast text product via forecast.weather.gov/product.php with site/issuedby/product parameters (product=REC for named-peak recreational forecasts, e.g. Mount Rainier)
Retrieve the FZL (Freezing Level Data/RADAT) product the same way for twice-daily balloon-sounding freezing-level data — note RTP is a regional max/min temperature and precipitation table, not freezing levels
Pair this with mountain-observation station data (summit/base weather stations tied to the WFO) for elevation-specific conditions
Known gotchas
These are legacy NWS text products (not the JSON /gridpoints API), so parsing requires text-product parsing, not JSON deserialization
Mountain observation stations are third-party owned (not NWS), so outages/inaccuracies must be reported to the station owner, not NWS
