|

* BahlaTabBar — barre d'onglets floutée, partagée par (tabs) et (org).
|

*
|
||||
* Une seule implémentation pour les deux parcours : le verre dépoli,
|
||||
* le calcul de safe area, le rendu des items et l'accessibilité sont
|
||||
* identiques. Seul le bouton central change, et il est optionnel.
|
||||
*
|
||||
* Usage :
|
||||
* <Tabs tabBar={(p) => <BahlaTabBar {...p} />}> // utilisateur
|
||||
* <Tabs tabBar={(p) => <BahlaTabBar {...p} fabRouteName="create" // organisateur
|
||||
* onFabPress={openCreateSheet} />}>
