Mirrors the owner's deck stack onto the spectator hex, DRY: - new shared _my_sea_deck_stack.html partial (mono DECK / dubbo DECKS by is_polarized) rendered by BOTH the owner picker (my_sea.html, flip_disabled= hand_complete) AND the visitor cross (flip_disabled=True). Owner markup is byte-identical, so its assertions hold. - the visitor's stack uses the OWNER's deck (everyone at @owner's sea plays the owner's deck — the visitor's own equipped deck is irrelevant), pinned top-left (--visit) across the table from the owner who deals bottom-right. - dubbodeck: the Gravity/Levity name flips above the face + upside-down to signal someone across the table is dealing. - the read-only FLIP (disabled ×) is hidden until its stack is hovered/focused, then eases in (same opacity 0->1 over 0.3s as the shared flip-btn-base reveal; inlined since _gameboard precedes _card-deck in the import order) so a permanent × doesn't clutter the stack. ITs: stack keys on the owner's deck (not the viewer's), dubbo renders 2 named stacks, FLIP is the disabled state, no stack when the owner has no deck. Owner deck-stack IT + FT stay green (identical markup).
