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.

Reporting only — the figures are the whole job.
Same strip, working as the filter. Press a tile to narrow the list; press it again to clear.

</div>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.

const rows = document.querySelectorAll('.hss-list li');
tiles.forEach((tile) => {
tile.addEventListener('click', () => {
const wasOn = tile.getAttribute('aria-pressed') === 'true';
const active = wasOn || tile.dataset.hss === 'All' ? 'All' : tile.dataset.hss;
tiles.forEach((other) =>
other.setAttribute('aria-pressed', String(other.dataset.hss === active)));
rows.forEach((row) => {
row.hidden = active !== 'All' && row.dataset.status !== active;
});
});
});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, the 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.
