/**
* Masonry live grid -- custom-group draggable layout.
*
* Verifies natural-aspect tile sizing and that a saved layout the current
* version cannot read is regenerated cleanly. The grid renders only for a
* custom camera group (here: "outdoor") on desktop; mobile keeps the static
* grid, which the @mobile block below guards.
