[throwaway probe B — inline span] closing-keyword reading for #8476 step 1 #8521

Throwaway target for the #8476 step-1 live reading. This issue is the INLINE-CODE-SPAN arm (control): the same throwaway PR will carry a closing keyword bound to this number inside single backticks. The expected reading is NO closing link, reproducing the measurement already recorded on the open PR referenced in the H7 header.

Closed immediately after the reading. No work is requested here.
