 * Program: a utilitarian program guide. A grotesk face, a fixed time column
 * and one row per gig; mono for times and counts, one orange accent.
 * Also the default when no theme is set.
 *
 * The layout below the colors is shared with Program's variants (Liner
 * Notes, Hard Bop, Evening, Broadsheet); each of their theme-*.css files
 * loads after this one and adds only colors, fonts and a few flourishes.
