    Shared FYI panel — Energy / Operation entries painted by StageCard.renderFyi
    in JS. PRV / NXT btns hang past the panel's left/right edges by -1rem each
    (see _card-deck.scss). Used by:
      - the fan stage (game_kit.html, paired with #id_fan_stage_block)
      - the sig select overlay (_sig_select_overlay.html)
      - the sea select overlay (_sea_overlay.html)
      - the tray sig-card tooltip (rendered into #id_tooltip_portal at hover time)

    `panel_id` is optional; when blank the wrapper is unidentified (used by the
    tray, which fills #id_tooltip_portal instead).
