/* Jackfish Bay — Great Lakes Area of Concern
   ---------------------------------------------------------------------------
   Palette is drawn from the subject: cold Superior water, oxidized copper-teal,
   mineral pale, bone. A single ochre marks the "impairment" register and is used
   only where degradation or caution is discussed — colour encodes state here, it
   is not decoration.

   Signature element: .layout carries a thin vertical rail that grades from ochre
   at the top to teal at the bottom, so the page furniture itself expresses the
   impaired -> recovering arc that the site is about.
