/* The landing hero's picture: two phone screens of the Stash app (the Projects list, and a
   project on its Features tab), drawn in HTML so they follow the site's palette and theme.
   A tidied-up version of the real app, not a copy of it: the fields and labels are the app's.

   Inputs are the site's tokens (site.css); every other colour is mixed from them:
     --ground --ink --ink-2 --tile --tile-2 --brand --brand-ink --spark

   Scale: everything is in em, and the stage's one font-size comes from the root's own width
   (container query units). Size the root with `width` and the screens follow. Under 520px of
   width the stage shows the Projects phone alone. */
