Made it so superscripts are displayed differently for (element, group: wide table cells) vs. (home, period: narrow table cells) by:
--pt_element.erb: adding <span class="wide"> if @ec_class == "pt_e_config_big"
--style.css: defining .wide sup
This could probably be done more elegantly…at least, redo
@ec_class == "pt_e_config_big" or "pt_e_config_small"
as e.g.
@ec_class == "wide" or "narrow"
