/* Arbiter site. Tokens from 2pc plugin/receiver-cpp/src/style.hpp, geometry from
   src/layout.hpp, tab strip and press ripple from src/widgets.cpp
   (pill_tab / draw_ripple): 0.4 s, 15% peak alpha, radius to the farthest
   corner, growing as sqrt(t). Near-black window, top bar with the mark and a
   centred tab strip, cards with a hairline border and a caption header,
   label/value rows, dark buttons with light text, status strip at the bottom.
   Flat: no shadows, no gradients, no transitions, no external requests. */
