/* AstroBar landing page.

   Dark, hairline-separated, one accent. The palette is taken from the app
   itself: #0A84FF is the blue the panel paints on active controls, #30D158 the
   green it uses for "Charging", #35C4E8 the cyan at the top of the app icon's
   gradient. Nothing else gets a colour.

   Type is the macOS system stack on purpose — this is a page about a Mac app,
   and SF Pro is the typeface of the product it is showing. */
