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.

}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, so a row never wraps into an orphan tile.
Two rules of honesty. Render a missing value as a dimmed em dash, never as zero. Keep units with the number they qualify.
In the filter form, each tile is a toggle button with aria-pressed, not a tab. Compute every count from the unfiltered set so the numbers don't shift as you filter.
