      summary: METAR / SPECI decoder with flight category
      description: 'Decodes up to 20 METAR or SPECI aviation weather reports (US and ICAO forms: wind with gusts and variable direction, visibility in statute miles or metres, CAVOK, RVR, present weather, cloud layers, temperature/dew point, altimeter, trend, RMK remarks) into structured fields and computes the FAA flight category (LIFR/IFR/MVFR/VFR). Every token it cannot decode is returned with its character offset and the status is unknown, never silently dropped; remark text it does not recognise is kept raw and does not change the status. Does not fetch weather, decode TAFs, or interpret forecasts. Reports must be uppercase as transmitted.
