// Dynamic pages (logic/page.h) as JSON for the web UI:
//   {slots: [{start: "08:00", bitmap: "Pikachu"}],
//    elements: [{type: "clock"|"date"|"ha"|"text", x, y, align: "left"|"center"|"right",
//                overlay: "top"|"box"|"invert", font, format, language: "nl"|"en",
//                decimals (-1 = as received), text, suffix, entity, attribute, factor,
//                scroll_width, scroll_speed, target ("YYYY-MM-DDTHH:MM"),
//                show: "number"|"duration"|"time"|"map", input_unit: "s"|"min"|"h",
//                auto_unit, absolute, map, bar_width, bar_height, bar_max, bar_frame,
//                day_offset}]}
//   type also "countdown", "stopwatch", "image", "bar", "life". Game of Life elements also
//   have start: "random"|"pattern"|"rotate"|"shuffle" and generations (0: no limit); the
//   other fields mean what logic/page.h says. Texts use the UTF-8 degree sign.
