/* ==========================================================================
   ImpTune — application shell + component layer on top of Pico CSS.

   Design direction: a workbench for a build pipeline (driver -> printer ->
   package), not a dashboard. Prose is set in the system UI face; every value
   the machine cares about (IPs, port names, INF driver names, PowerShell
   commands) is set in monospace. That split is the visual identity.

   Theme selectors mirror Pico's own so equal specificity + later source order
   wins:  light = :root:not([data-theme=dark]) ; dark = the two dark selectors.
   `data-theme="auto"` is not `light`, so it follows the OS preference.
