I've been catching CSS Grid Lanes in the socials this week, but somehow had it in my head that it was to do with the gaps (the lanes) between the grid.
It's not, it's masonry (which, why not display: masonry 🤷
There's a also a decent (albeit stiff) video on how it works.
TL;DR: mostly you can swap display: grid for display: grid-lanes (but Jeremy goes further to actually add the CSS support check first).
