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.
Tiles that share one ground, like this strip shares one border color.

</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.

})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. One column, then two from 21rem, then four from 42rem, so a row never wraps into an orphan tile.
Tile anatomy. A mono uppercase label, a large tabular-nums figure, and a one-line qualifier underneath.
Two rules of honesty. Render a missing value as a dimmed em dash, never a zero. Keep units with the number.
The filter form. Each tile becomes a button with aria-pressed, not a tab. Compute counts from the unfiltered set so they don't move while the list narrows.
The first two paragraphs are the prompt verbatim; the bold-led paragraphs summarize its remaining sections.
