/* Device Portal design language.
   Brand: BrainLit blue #004177 (hover #00335e), navy #052847, accent #8ABAFF, as in the touchscreen
   and config tool apps. Type: Inter for the UI, a system monospace for hostnames and versions.
   Surfaces: a cool grey canvas, white cards with a 14 px radius and a soft shadow.
   Chrome: a light, blurred top bar on portal pages; a navy bar on a device session, so the
   dark frame says "you are inside a device". */
