+/* Keep the last terminal row clear of the cell border/focus ring in a grid.

+ * getComputedStyle(pane).height — which xterm's FitAddon reads to compute rows —
+ * returns the PADDING-box height and double-counts the pane's own padding, packing
+ * one extra row that overruns into the border (overflow +6px). content-box makes
+ * that height report the CONTENT box, so FitAddon drops the phantom row and the 6px
+ * padding becomes real clearance. (Single mode keeps padding 0 so the terminal
+ * still fills to the key-bar.) */
