/* ---------------------------------------------------------------------------
   Multi-line signatures (one parameter per line).

   When a signature is wrapped, Sphinx renders each parameter as a <dd> inside
   a nested <dl>. The Read the Docs theme styles every <dl>/<dd> with borders,
   background tint and vertical margins, which leak into the signature and draw
   ugly "lines" between parameters. Flatten that nested list so the parameters
   read as a clean indented column.
