Enlarge list text on dense two-column slides

Browse source 
Two-column slides share one text size driven by the busier column, so a
19-item column rendered the items tiny while fixed-size title and headings
dominated the slide. For dense columns (>12 items) spend less height on the
title, column headings and inter-item gaps, and use a tighter top/bottom
margin, so the list items render larger and stay readable. Sparser slides
keep their original proportions.
