I posted the link because of all of the unusual wing layouts. I've seen most of them before but as a collection in simple diagram form it is mind expanding.

They also added two small retractable surfaces called a Moustache canard, with fixed double-slotted LE slats and retractable double-slotted flaps. These were fitted just behind the cockpit and increased lift at low speeds.

Moving the elevons downward in a delta-wing aircraft increases the lift (force), but also pitches its nose downward. The canards cancel out this nose-downwards moment..........
I've never hear of a Moustache canard before either.

A pair of small vanes mounted near the nose are part of an active vibration damping system that smooths out the otherwise bumpy low-altitude ride.
A true canard acts like a tail wing but in opposite direction to help balance the center of lift and center of gravity.

A tail wing holds down the tail against the moment arm of lift created by the main wings.

Hence a canard holds up the nose against the moment arm of lift by the main wings.

From this a canard provides lift, a strake, chine or vane mostly provides stability, and a Moustache canard combines many of these flight characteristics.

I guess.

Does that sound right?
