[UX/UI] More flexible layout for homepage featured collection cards

[wrenaria]

Request Details

This is a low-priority enhancement request that is okay to defer until post-release if needed. The original vision for homepage featured collection card layout was a little more dynamic than current implementation to allow more flexibility in number of cards that can be selected for the homepage features.

Currently, if only two cards are selected, they still display in a 3-column format, leaving a blank space for the the empty column. This looks unpolished/unintentional.

Details of preferred layout are below.
