/* ============================================================================
   Forecast Flakes — the winter room of the Forecast network.

   Same Interstate sign system as the rest of the network, turned down to a
   winter night: the paper goes from reflective buff to packed snow, the ink
   goes to midnight, and BLUE leads instead of green because winter weather is
   a services problem — what closes, what needs plowing, when it starts.

       SNOW    #2f57bf   the accent. It is the 6-inch band of the NWS snowfall
                         scale, so the site's accent and its map legend are
                         literally the same blue.
       ICE     #7a3fa8   freezing rain and sleet, the purple end of that scale
       GREEN   #04663d   guide/wayfinding, unchanged from the network
       RED     #b0242e   warnings, unchanged

   Charts reuse the palette validated for the network's climate pages: the
   observed series in Interstate blue against a de-emphasis gray, and an RdBu
   diverging ramp with an achromatic midpoint for anomalies.
