Scaffold the Next.js SaaS foundation

app-bootstrap

The branch adds a coherent initial Next.js 14 App Router scaffold with TypeScript, Tailwind, Prisma/SQLite bootstrap, shared UI primitives, and the required `/`, `/login`, `/signup`, and `/app` routes. README and `.env.example` document the expected local setup and required variables. I found no generated artifact files in the branch diff. `tsc --noEmit --incremental false` and `prisma validate --schema prisma/schema.prisma` both passed; `next lint` could not be verified in this read-only sandbox because Next.js tries to rewrite `next-env.d.ts` during startup checks.

Create the authenticated dashboard shell

app-shell-and-nav

The branch cleanly implements the authenticated `/app` shell with persistent sidebar navigation, adds the required dashboard/lists/categories/settings destinations, preserves auth gating through both middleware and `requireCurrentUser()` in the `/app` layout, and introduces meaningful empty-state content with a first-list CTA. The diff is focused on the task, contains no generated artifacts, and existing automated tests pass. `npm run typecheck` still fails, but the failures are in pre-existing auth typing files outside this diff.

Implement Prisma schema and credentials authentication

auth-and-data

The branch adds the requested Prisma models, checked-in SQLite migration, Prisma client bootstrap, credentials-based signup/login/logout flow with hashed passwords, and `/app` route protection. The diff is coherent and focused on the task, the included auth utility tests pass, and there are no irrelevant generated artifacts in the branch.

Implement grocery list, item, and category workflows

lists-and-categories

Implements the core MVP workflows coherently on top of the existing authenticated app: users can create/rename/delete lists, manage items including quantity/unit/category/completion state, create custom categories with default categories provisioned on first use, and filter or group list items by category. Diff is focused, no generated artifacts were added, and both `npm test` and `npm run typecheck` pass. `next build` could not be verified in this read-only worktree because Next.js could not create `.next`.

Build the public presentation site

marketing-site

The branch cleanly upgrades the home page into a credible SaaS landing page with a clear hero, feature section, pricing teaser, FAQ/trust content, and repeated CTAs to `/signup` and `/login`. The diff is focused to the landing page and global styling, no irrelevant/generated artifacts are present, and the changes align with the acceptance criteria. I could not run `build` or `typecheck` in this worktree because project dependencies are not installed (`next` and `tsc` were unavailable).

Finish MVP polish, validation, and local run quality

qa-and-polish

No merge-blocking findings. The diff is focused on the task: README now documents fresh setup plus demo verification flow, the seed adds ready-to-demo checked/open items, validation and user-facing error/success states were added across signup/login/list/category/item flows, and pending/disabled submit states were introduced consistently via `SubmitButton`. A small automated test slice was added for shopping validation/redirect helpers, no generated artifacts are present, and `npm test` plus `npm run typecheck` passed. Residual gap: `npm run build` could not be fully verified in this read-only sandbox because Next.js could not create `.next`.
