fix: a page number that reads as a 1, and Word's stacked split button

The glyph was a stem on a base with no flag, so it read as a down-tack rather
than the digit it stands for.

A caret welded to the right of a big button floated at icon height, beside the
label instead of with it, on every menu button of the Layout tab. Big split
buttons stack now, as in Word: the icon runs the command, the label and its
caret open the menu. Measured: every label in a group still tops at 87px.
