The flex leaves the glass's back plane on the left and must fold ~180 deg
to dive into the cavity toward the breakout. A safe bend radius makes
that loop ~4 mm deep, too deep for the 1 mm foam gap, so it fouled the
rigid bracket. Open the bracket's left frame member and the foam's left
border over the FPC span, aligned with the body's existing slot, to give
the U-turn room. Re-adds the relief dropped in c4320e2, correctly scoped.
