  /* The chat's theme (lane uxt, 13 Oct 2026; owner: "make sure theme of mouji chat is completely aligned with uj
     chatbot"). UJ's own MoUJi is a LiveChat "smooth" widget: a light grey canvas, white cards with 20px corners,
     12px buttons, round grey head controls, near-black text, the system font, a white tab launcher with an orange
     label, light only. The same values as the web chat widget's soft look (Nova --grey-300/400/500/600/900), so
     the Hub's chat and the widget read as one product. Measured: ink on the canvas 15.1:1, on a card 19.5:1;
     muted 5.5:1 on the canvas; control text 10.9:1 (hover 5.3:1); field edge 7.1:1 on white, 5.5:1 on the
     canvas; the tab's #B8460B label 5.4:1 on white. MoUJi's white text on #F26522 is 3.15:1 (fails AA), so the visitor's line stays black on
     orange (6.6:1). */
