/* Barometra on the web — the app's own language, not a generic document theme.
 *
 * The page is a sky: the same four-stop gradient the app paints behind every
 * screen (skyGradients.calm in src/theme/tokens.ts), fixed so it behaves like
 * a horizon rather than scrolling wallpaper. The text sits on one floating
 * glass sheet, the way every card in the app does.
 *
 * No webfonts on purpose. A site whose whole subject is "nothing about you
 * leaves the device" should not phone a font CDN to render that sentence, so
 * the stack leans on ui-rounded — SF Pro Rounded on Apple platforms, which is
 * the closest system answer to the app's Nunito.
