/* Atlas — widgets (static/js/explore/widgets/, docs/WIDGETS.md).

   A widget is a sheet of cream paper laid on the page, a torn strip of its
   colour across the top and a red label pinned over the title; inside it,
   the drawing is cut from flat colour — every shape throws a small hard
   shadow, the way paper laid on paper does — and the controls are the
   Atlas's own chips and buttons.

   Every colour is a token from static/explore/tokens.css. The widget's own
   colour is the theme family (--theme-h, set by the page or by the spec's
   hue), or the place's / the era's with .by-place / .by-era; each part of a
   drawing that has a colour of its own (a side on a map, a ring on a clock,
   a layer of a tower) declares its own --theme-h and gets the theme family
   worked out again right there (tokens.css, "⚠️ A custom property…"). So the
   dark theme is the same drawing, and the contrast test covers the text. */
