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.

Colors come from shared theme tokens — --surface, --ink, --border, --accent and friends — so this CSS carries no palette of its own. Use Runnable file to copy the tokens along with it.
.hss-strip {
display: grid;
gap: 1px;
background: var(--border);
border: 1px solid var(--border);
border-radius: var(--radius);
overflow: hidden;
grid-template-columns: 1fr;
}
@container (min-width: 21rem) { .hss-strip { grid-template-columns: repeat(2, minmax(0, 1fr)); } }
@container (min-width: 42rem) { .hss-strip { grid-template-columns: repeat(4, minmax(0, 1fr)); } }
.hss-tile { background: var(--surface); padding: .9rem 1rem; min-width: 0; }
.hss-tile .l { font: 500 .8125rem/1.3 ui-monospace, monospace; text-transform: uppercase; color: var(--dim); }
.hss-tile .v { font: 700 1.6rem/1.2 system-ui; font-variant-numeric: tabular-nums; }
.hss-tile .v.none { color: var(--dim); }
.hss-tile[aria-pressed="true"] {
background: color-mix(in srgb, var(--accent) 14%, var(--surface));
}const tiles = document.querySelectorAll('.hss-strip button');
tiles.forEach((tile) => {
tile.addEventListener('click', () => {
const wasPressed = tile.getAttribute('aria-pressed') === 'true';
const value = wasPressed ? 'all' : tile.dataset.state;
tiles.forEach((other) =>
other.setAttribute('aria-pressed', String(other.dataset.state === value)));
document.querySelectorAll('.downloads li').forEach((row) => {
row.hidden = !(value === 'all' || row.dataset.state === value);
});
});
});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.
The full prompt continues with sections on pinning column counts, tile anatomy, two rules of honesty (render a missing value as a dimmed em dash; keep units with the number), the filter form, computing counts from the unfiltered set, and using aria-pressed rather than tab roles.
