{{-- Locale bar for LocaleTabs: switches which locale copy is shown via `x-show` on each copy's wrapper (set on the ancestor Group by LocaleTabs::make()). No Livewire round trip. Unlike LocaleSwapEditor's bar, this one doesn't talk to any JS plugin or mirror any state: every locale copy is a REAL Filament field, already wired to its own wire:model, so there is nothing to copy on switch — just toggle which one is painted. Same visual design as the hero bar on purpose (docs/CLAUDE-PANEL-RENDIMIENTO.md §15), so every locale switcher in the panel looks the same regardless of which mechanism is behind it. --}}
