.actions sets display:inline-flex (correct for a button container), but it was applied directly to <td class="actions">, pulling the cell out of the table row box so its bottom border rendered ~1px off from the other columns. Override td.actions back to display:table-cell and space multiple buttons with a margin instead of the flex gap. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
