 * Protn — one stylesheet for the whole site.

 * The app carries its look in four shared pieces (ScreenGradient, Node, the

 * copied from constants/themes.ts and constants/tokens.ts, and nothing below
 * redefines a colour or a weight inline.
 *
 * Dark only. The app ships userInterfaceStyle: "dark" for v1, so there is no
