/* SP Avatr — support site.
   One stylesheet, no build step, no external assets, no webfonts.
   Palette is sampled from the app icon: a deep navy ground and the cyan of the
   wireframe glow. Dark is the product's look, so it is the default; a light
   palette is defined for readers whose OS asks for one. Every colour is a token
   defined on bare :root first — none is only ever set inside a media query. */
