   rather than blending into the tag text, a bolder/larger tag name, and a
   clearer selected state (red-tinted background AND a red checkmark) so a
   checked pill is unmistakable at a glance.

   Column pass: laid out as a grid (same pattern as the Merge Tags modal's

   tags reads as an organized, scannable block of columns instead of a
   ragged multi-line wrap where tag boundaries are hard to follow. */
