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.

const wasPressed = tile.getAttribute('aria-pressed') === 'true';

tiles.forEach((other) => other.setAttribute('aria-pressed', String(other === tile && !wasPressed)));
let shown = 0;
rows.forEach((row) => {
row.hidden = filter !== null && row.dataset.rowStatus !== filter;
if (!row.hidden) shown += 1;
});
status.textContent = filter
? `Filtered to ${filter}: ${shown} of ${rows.length}. Press the lit tile again to clear.`
: `Showing all ${rows.length} downloads.`;
});
});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 rather than letting auto-fit choose them: one column, then two, then four. A row that wraps to an odd count leaves a dangling tile.
Two rules of honesty. Render a missing value as a dimmed em dash, never as zero. Keep units with the number.
In the filter form, each tile is a toggle button with aria-pressed, not a tab. Compute every count from the unfiltered set, so pressing a tile never changes the numbers on the others.
