Marketplace Home Screen

Composite scrollable screen made of a banner carousel, category strip, trending deals, summer-sale tile, special offers, and the main product grid/list. Watches marketplaceControllerProvider for the list state.

1. Top bar with search + cart + notification triggers.
2. MarketplaceCategoryList chips toggle category filters.
3. MarketplaceFilterBar exposes Filter / Sort / Grid toggles via bottom sheets.
4. MarketplaceProductList renders the result and triggers loadMore on near-bottom scroll.
5. warningMessage banner shows after auto-recovery and is dismissible via clearWarning.

• Pagination trigger fires when scroll position passes ~80% — tweak in the list widget, not the controller.
• Hero widgets (banners, summer sale) read from local sample data; they are not yet backed by a CMS service.
• Grid vs list toggle persists for the controller lifetime (not across kills).

Long screen (~540 lines) — keep new sections as standalone widgets in widgets/ to avoid the file ballooning further.
