/* diagnostics.css --- v3 runtime diagnostics panel styling.
 *
 * W2 facet, wave 2. Styled inset that sits inside the Piano Keys body
 * (which is itself a fixed overlay, already monospace via its own rules).
 * Integration: concatenated into logan-os/v3/v3.css by W5 (append-only).
 *
 * Vocabulary:
 *   .diagnostics-panel      top-level inset
 *   .diagnostics-header     summary row (counts + ISO timestamp + re-run)
 *   .diagnostics-summary    "<pass> pass / <fail> fail" label
 *   .diagnostics-live       live state grid
 *   .diagnostics-list       pass/fail assertion rows
 *   .diagnostics-row.pass   subtle green checkmark row
 *   .diagnostics-row.fail   soft red cross row with mono error detail
