The snapshot filter's placeholder had no rule at all, so it fell through
to the browser default — a grey chosen for light backgrounds, rendering
near-invisible against a dark panel. "Filter by app, host, or backup id"
is the one hint telling you what the box accepts, so losing it costs the
control its explanation.
Written against --text-rgb rather than a fixed grey so it follows the
theme: white at 60% on nebula and dark-blue, dark at 60% on light, where
a hardcoded #ccc would have been unreadable the other way round. Firefox
dims placeholders on top of the colour, so opacity is pinned to 1 and the
alpha above owns the result. Slightly brighter than the task filter's
0.4, and in line with the shared .form-control rule's effective value,
because this string is instruction rather than decoration.
