/* Atlas — walks (static/js/explore/walks.js): the place's walks as cards,
   and one walk: its paper map, the scrubber, a coloured card per stop, the
   guesses and the score.

   Colours come from the tokens (static/explore/tokens.css): the place's own
   (--place-*) on the map's route, its pins and the cards; a stop's card
   takes the colour of what it belongs to — an era's (--era-*, .by-era), a
   culture theme's (--theme-*, .by-theme), else the place's. The map's own
   inks (water, a park, a wall) have no data file to carry a hue, so they
   are here, as tokens.css keeps the history layers': the label inks
   (--wk-*-ink) are checked for contrast on the paper and on their own
   shape by tests/js/explore-contrast.test.mjs. */
