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.

}
for (const row of list.children) {
row.hidden = next !== "all" && row.dataset.status !== next;
}
});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. Keep two rules of honesty: render a missing value as a dimmed em dash, and keep units with the number. In the filter form, compute every count from the unfiltered set and use aria-pressed on the tiles rather than tab roles.
The five-tile filter row gives "All" its own full-width tile until there is room for five columns, so labels and counts never overflow their tiles.
