      "interpretation": "Per the BGaming provider playbook, this rail position is a round-history/session-log section, not a characteristics/rules section — in a fresh demo session with no prior round history it is expected to show nothing, so this is treated as a normal empty session state rather than an uncaptured game feature."

Residual risk: the five shell colors (purple/red/blue/orange/green) are visually similar in saturation to a deuteranope/protanope viewer and rely on shape+position recognition rather than an independent text label per shell — screen-reader/alt-text support should name each shell's color explicitly.",
