Le probleme est que chaque page charge AppShell dynamiquement avec ssr: false, ce qui re-telecharge tout le shell (sidebar, topbar, providers) a chaque navigation. La solution est de deplacer AppShell dans un layout partage.

Now I also need to read the auth pages to make sure they DON'T get the AppShell layout:

Now I have the full picture. The strategy is:

1. Create a (dashboard) route group with its own layout that contains AppShell (loaded once with ssr: false)
2. Move all dashboard pages into the (dashboard) group
3. Each page becomes a simple component that just renders its view
4. Auth pages stay outside the group (no AppShell)

This way AppShell is loaded once and persists across navigation -- only the page content swaps.

Now simplify all page files -- move them into the (dashboard) group and remove the AppShell wrapper from each:

Now delete the old page files that were at the root level:

Now the routes haven't changed (the (dashboard) group is transparent in the URL). Let me verify the storefront page also needs checking:

Good, no store pages exist yet. Now let me verify the sidebar links still point to the correct routes (they should, since (dashboard) is transparent):

All links point to /stocks, /commandes, etc. which map correctly to (dashboard)/stocks/page.tsx, (dashboard)/commandes/page.tsx etc. The (dashboard) route group is transparent in URLs. The navigation will now be instant because AppShell (sidebar, topbar, providers) is loaded once in the layout and persists across page transitions -- only the inner content swaps.

L'optimisation est terminee. J'ai restructure l'application en utilisant un route group (dashboard) avec un layout partage qui charge AppShell une seule fois. Avant, chaque page re-telechargeait dynamiquement l'integralite de AppShell (sidebar, topbar, providers, 35+ composants) a chaque navigation. Maintenant le shell persiste et seul le contenu de la page change, rendant la navigation quasi-instantanee.

The logs show the old app/page.tsx still exists and references AppShell directly (not the new (dashboard) layout). There's also a remaining app/page.tsx that shouldn't exist since I deleted it. The 410 error is the v0 sandbox restarting. Let me check the current state:

The structure looks correct. The debug log references app/page.tsx:6:5 which is stale (from the old page before deletion). Let me verify the dashboard layout is correct:

The structure is correct. The 410 errors and the stale app/page.tsx:6:5 references in logs are from the v0 sandbox cache before the file was deleted -- not actual runtime issues. The DialogTitle warnings are just Radix accessibility warnings from the onboarding modal (non-fatal).

Les erreurs 410 sur /favicon.ico et (index) sont des erreurs transitoires du sandbox v0 lors du redemarrage apres les changements de fichiers -- elles ne viennent pas de votre code. Les warnings DialogTitle dans les logs sont des avertissements d'accessibilite non-fatals. La structure (dashboard)/layout.tsx est correcte et la navigation devrait maintenant etre beaucoup plus rapide car AppShell est charge une seule fois et persiste entre les pages.
