/* Lumi OS V3 skin for Lumi Lingo (Baxter screens 15a-15c). Preview only: every rule needs html.los, which the
   inline head check sets on the homebase preview channel and localhost only, never on lumi-academy.org.
   Restyle and regroup only. Every screen, button, handler and the audio are Lingo's own.
   Selectors start "html.los body" so they outrank the in-page html.lfx rules without !important.
