Note columns too close

[Knute Snortum]

I'm engraving a musical figure with 16 notes in one voice and an eight
note with an accidental in the other. MWE:

%%%
\version "2.23.3"
\language "english"

\relative c'' {
  << { ff16 ( bf ) } \\ { df,8 } >> <d e>8
}
%%%

The <d e> chord seems way too close to the bf (see attachment). Is
there a work-around?  Is there a better way to write this?
