/*
	Devices data grid (#179).

	Scoped entirely under #device-table.device-grid / .device-table-scroll so
	nothing here leaks into other pages. main.css sets global element rules
	(table { display: block }, td/th { display: inline-block }) that destroy
	real table layout, so this file explicitly restores table display roles
	for the grid. Colors come from the shared theme tokens in main.css, which
	the html[data-theme='dark'] overrides retarget automatically.
