Highlight tags with no triggers

Frames tags that have no firing trigger assigned with a dashed outline, so you never ship a dead tag.

Code to copy

/* Rows whose trigger cell is empty or shows a dash */
tr:has([aria-label*="No firing triggers"]),
tr:has([title*="No firing triggers"]) {
  outline: 2px dashed #EA4335 !important;
  outline-offset: -2px !important;
  background: rgba(249,171,0,0.10) !important;
}
