a second face opposite the first face; and a top edge defining a first raised portion of the door panel, a second raised portion of the door panel, and an open space extending between the first raised portion and the second raised portion; a plurality of rollers affixed to the door panel, wherein each roller of the plurality of rollers has an axis of rotation normal to the first face of the door panel; and a soft-close assembly secured within the open space between the first raised portion of the door panel and the second raised portion of the door panel, the soft-close assembly comprising at least one catch; and a track enclosure, comprising: a roller track positioned within the track enclosure, the plurality of rollers being movably disposed upon the roller track; and at least one soft-close actuator positioned within the track enclosure, a first soft-close actuator of the at least one soft-close actuator being configured to engage with a first catch of the at least one catch of the soft-close assembly to provide soft-close functionality in a first direction. ### Claim 12 (depends on 11) The sliding door system of claim 11, wherein: the roller track comprises an elongate track with a convex curvature, and each roller of the plurality of rollers comprises a corresponding concave curvature. ### Claim 13 (depends on 11) The sliding door system of claim 11, wherein the track enclosure further comprises: an enclosure bracket comprising: a top wall; a first vertical wall configured to be disposed over at least a portion of the first face of the door panel when the plurality of rollers of the sliding door are arranged on the roller track within the track enclosure; and a first bottom wall that extends from the first vertical wall toward the first face of the door panel when the plurality of rollers of the sliding door are arranged on the roller track within the track enclosure; and a covering plate removably securable to the enclosure bracket, the covering plate comprising: a second vertical wall configured to be disposed over at least a portion of the second face of the door panel when the plurality of rollers of the sliding door are arranged on the roller track within the track enclosure; and a second bottom wall extending from the second vertical wall toward the second face of the door panel when the plurality of rollers of the sliding door are arranged on the roller track within the track enclosure. ### Claim 14 (depends on 13) The sliding door system of claim 13, wherein the first bottom wall of the enclosure bracket comprises the roller track. ### Claim 15 (depends on 13) The sliding door system of claim 13, wherein the second vertical wall of the covering plate comprises the at least one soft-close actuator. ### Claim 16 (depends on 13) The sliding door system of claim 13, wherein: the top wall of the enclosure bracket comprises a channel with a shelf extending from a bottom channel wall of the channel;
