Hairline stat strip
A row of stat tiles joined by hairlines that are grid gap, not borders — the container paints the border color and the tiles paint the surface, so separators never double up or break when the row wraps — in a reporting form and in a second form where each tile is the filter for the list beneath it.

});
});Build a strip of statistic tiles that reads as one joined instrument panel rather than a row of floating cards.
The separators between tiles must not be borders. Make the container a CSS grid with gap: 1px and give the container itself the border color as its background; each tile then paints the surface color on top. The 1px of container showing through the gap is the hairline. This is the entire pattern: real borders double where two tiles meet and leave a stray edge when auto-fit wraps the row, and a gap physically cannot do either.
Pin the column counts
Step the columns 1, then 2, then 4 at fixed breakpoints instead of auto-fit, so a strip never ends on a lone orphan tile.
Two rules of honesty
Render a missing value as a dimmed em dash, never a zero. Keep the unit with the number.
The filter form
Each tile becomes a toggle button with aria-pressed, not a tab. Compute every count from the unfiltered set, so pressing one tile never changes the numbers on the others.
Fixed here: labels in the five-tile filter row wrap instead of clipping ("Queued 2 downloa…" on the current site); the row steps 2 → 3 → 5 columns.
