   Palette is taken from the app itself: the amber is the same #FFB74D that
   app/src/main/res/values/colors.xml uses, chosen there because it sits
   against photographs without competing with them. Here it behaves as
   emitted light — the frame glows onto the page — rather than as a flat
   accent, which is why it appears mostly in gradients and shadows.
