/* TENFOUR pad — identity v3: the Aurora skin.

   The pad wears the same design language as the in-game alert card
   (web/src/variations/V1Aurora.css, tokens from nn_policejob/DESIGN.md):
   smoked near-opaque panels on a blued near-black chassis, a 1px specular
   ring catching light from the top-left, and ONE hue per surface carrying
   its priority — red alarms, amber cautions, patrol blue acts, grey informs.
   Signal yellow stays the product's own colour: it marks TENFOUR itself,
   never an action.

   Type: Chakra Petch for the console, Rajdhani for reading, JetBrains Mono
   for codes, timestamps and anything a radio says.

   Themes are custom-property sets on :root, swapped by [data-theme]. The
   chassis is shared; a trade swaps the accent and the glow. The game server
   picks with Config.Link.Brand.theme and may still override the single
   action colour with Brand.accent.

   No chrome bar — the unit strip at the top carries identity, connection,
   clock and the two toggles. One column on a phone; at 720px the dispatch
   board docks under the console; at 960px it docks on the right. */
