  /* Brick maroon, xterm-256 cube index 167 (channels 4,1,1) — exact, so the
     terminal and web can never drift. Replaces the steel silver #afafaf: the
     silver matched RPS's monochrome glyphs but was the catalog's only
     zero-saturation accent, which read as disabled beside seven saturated
     ones. Deliberately not a pure red — seat 0 is #ff0000 and RPS shows seat
     colors constantly, so the page chrome must not be mistaken for a player. */
