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.

</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.

tiles.forEach((tile) => {
tile.addEventListener('click', () => {
const wasOn = tile.getAttribute('aria-pressed') === 'true';
const state = wasOn ? 'All' : tile.dataset.state;
tiles.forEach((other) =>
other.setAttribute('aria-pressed', String(other.dataset.state === state)));
renderList(state); // counts always come from the unfiltered set
});
});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 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.
