+Run that with a narrow or unset `COLUMNS`. Rich sizes its output to the terminal,
+so a wide terminal executes render branches a narrow one does not: this suite
+reports 93 percent unset or at 80 columns and 95 percent at 140. CI has no tty and
+sees 93, so a wide local terminal will suggest roughly twice the headroom that
+actually exists.
+
 CI enforces that dash check, the coverage floor, and a packaging job that
 asserts CLI help text and examples, so changing a banner or an example string
 can fail the build. `CONTRIBUTING.md` carries the full local suite.
