/* kit.css: the look every motion visual shares (newsroom/visual-kit/kit.css). build.py puts it first in styles.css and the
   visual's own CSS after it.
   Palette: dark card, white text, indigo and cyan for marks, rose only for "not confirmed / not stated", amber only for a note.
   Two frames on one DOM: tall (the fixed 1060px frame below 900px wide) is the base; wide (the block's aspect ratio, 5:4 or
   16:10 on screens 900px and wider) overrides it in the media query near the end. The wide query must match WIDE_QUERY in kit.js.
   Wide sizes are in rem and the root font size scales with the frame, so the wide design is one fixed composition. */
