Toolbar glyphs drop from the 300 to the 200 Lucide weight and rest on
zinc-300 instead of full white, coming up to foreground on hover. The sync
popover pins its text to the start (the editor's centered alignment leaked
in), loses its bold title, and puts its actions in one right-aligned row.

The map card was 262pt wide with 260pt of contents, so the slack landed on
the right of the side toggle. Its width is derived from the tile, gap, and
toggle now, so both sides get the same 4pt.
