/* ============= Nightly / Weekly Tests — failure deep-dive modal ============
 *
 * Two pieces:
 *   1. `.nt-fx-count` — the small clickable Fail/Error numbers in the run
 *      table. Visually almost identical to the plain numbers they replace;
 *      the only difference is an underline + hover state, so a card with no
 *      failures looks completely unchanged.
 *   2. `.nt-fx-modal-*` — the popup itself, styled after the pattern the
 *      Multi-Arch Release tab already uses for its "Failure context" modal:
 *      a header meta grid, a violet "AI Investigation" panel, then a list of
 *      per-test detail cards. Reuses the HUD's existing CSS variables
 *      (--card-border, --text-secondary, --status-fail, ...) rather than
 *      introducing a palette.
