Conversation bubbles with a speaker-colored spine and a fixed metadata gutter.
Layout · pattern 15 of 40
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.

for (const item of items) item.hidden = Boolean(active) && item.dataset.hssItem !== 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 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.
Conversation bubbles with a speaker-colored spine and a fixed metadata gutter.
Text printed over unreviewed artwork, scrimmed to an alpha that can be written down rather than guessed.
A container with no artwork draws one from up to four member tiles, grid tracks following tile count.
