/* VW_WATCH_TOGETHER_PM_FLUID_STATE_FINAL_V3_15R6R1
   Corrected final additive adapter.

   R6 failure diagnosis:
   1) List Hide Video used the R3 global class `vw-premium-video-hidden`.
      R3 intentionally auto-restores video whenever PM is open but no thread is open,
      so list hide was immediately undone.
      R6R1 uses its own `vw-r6-list-video-hidden` state for the PM list.

   2) Keyboard header relied only on cascade timing.
      A14R1 proved the final 3-column geometry, so R6R1 also applies that geometry
      directly from JS with inline !important while keyboard/tight states are active.

   R4R1 Player sheet and R5R1 GIF geometry remain unchanged.
