/* DataRipple sales presentation. The opening slides stay navy. Everything after them (demos, Rolodex, wrap up, dialogs, the end card) is the light
   DataRipple look of the Book a call funnel: white page, navy header, white bordered cards. Clips keep their own navy backdrop (#131b26), so a video
   is a dark card on a light page with no visible frame of its own. Red = the one primary action and the current place; green = played; everything
   else is grey. 3px buttons, 6px rows, 10px cards, Ubuntu throughout.
   --u is one design pixel of a 1920 x 1080 slide (set by sp.js from the window), so slides and the wrap-up scale as one picture. */
