tag columns are the WHOLE rendered tag: h/j/k/l walk taglines, the path selects but never edits

+# h/j/k/l ON A TAGLINE move focus BETWEEN taglines. A tag is a place in the
+# LAYOUT, not just a line of text, so the four letters walk the layout and land
+# on the neighbour's TAG (top row of the window), still in normal mode — you
+# walk the taglines and never drop through a body. They run the SAME
+# Left/Down/Up/Right builtins `SPC w h/j/k/l` and `Ctrl-w h/j/k/l` run: one
+# focusDir, three routes to it. The ARROWS keep the in-tag grapheme motion, so
+# no capability was traded away.
+#
+# Evidence is the `cursor=` header (the ACTIVE pane's cursor, which while a tag
+# is focused sits on THAT pane's tag row) plus the tag text itself: a focused
+# tag renders its owner's mode, so NOR means the tag is in normal mode and the
+# pane we left is back in its body mode.
