Plan step 35: <x-grid :columns gap min-item>. The column count per breakpoint is written as five inline custom properties, each filled from the nearest smaller breakpoint, so a nested grid never inherits its parent's; min-item fills a row by the room the grid has, and with columns the counts become a ceiling.
