What content and styling can I control in the Header and Footer Panels of SW Pillar Section?

In SW Pillar Section, use the Header content fields for headings, rich text, and buttons above the main columns. Use Footer Content for the same types of content below the columns. Style the two areas separately with Header Panel Settings and Footer Panel Settings. Each panel has background, border, effect, alignment, and spacing controls. Changes to those panels do not replace the separate settings for the primary column, secondary column, form, media, or list.
