/* ── Bootstrap 5.3 color-utility backfill ───────────────────────────────────
   The vendored Bootstrap is 5.1.0, which lacks the `-subtle` background and
   `-emphasis` text/border utilities introduced in 5.3. Views use them widely
   (e.g. Medium/Low priority badges, visibility tags); on 5.1 the class is a
   no-op, so the badge falls back to its default white text on a transparent
   (white) background and becomes invisible. These are the official 5.3.3
   light-mode values; remove this block if Bootstrap is upgraded to ≥ 5.3. */
