/* The recovery link inside a rate-limit error.

   A rate-limit message is the only error here the visitor cannot fix by
   correcting the field above it, so its contact link is the action, not
   a footnote — it gets its own line and a button-like target rather than
   inheriting the error text's 13px red run-on. It stays in the error's
   red family, because it is still an error being reported.

   line-height on .gate-error is left alone: this is a block child, and
   raising the paragraph's leading to suit it would loosen every
   single-line field error on the form. */
