+# Monthy Tracker Agent Handoff
+
+Use this file as the starting point for any new agent. It summarizes the repo state, the important files, and the non-obvious behavior so you can continue without re-discovering basics.
+
+## What this app is
+
+- Single-user, local-first monthly expense tracker.
+- Stack: Next.js App Router, Prisma, SQLite, Ollama for offline AI.
+- Main views: dashboard, add expense, income/paychecks.
+- Goal: track expenses and paychecks, then generate private monthly summaries and recommendations.
+
+## Current state
+
+- Dashboard data is loaded from `/dashboard?month=YYYY-MM`.
+- Monthly insight generation lives in `src/lib/insights.ts`.
+- The app is currently working with the local dev DB at `file:./prisma/dev.db`.
+- Seed data exists for February 2026 and March 2026.
+- The frontend shows the current month by default, so if data looks missing, check the active month selector first.
+
+## Important files
+
+- `src/components/home-dashboard.tsx` - dashboard UI, fetches dashboard and Ollama status.
+- `src/lib/dashboard.ts` - aggregates totals, breakdowns, recent expenses, and comparisons.
+- `src/lib/insights.ts` - builds the model prompt, calls Ollama, stores fallback/model insights.
+- `src/app/dashboard/route.ts` - dashboard API route.
+- `src/app/backup/database/route.ts` - SQLite backup endpoint.
+- `src/lib/date.ts` - month/date helpers; month filtering uses local date strings.
+- `prisma/schema.prisma` - data model source of truth.
+- `prisma/seed.ts` - local seed script.
+- `README.md` - setup and runtime notes.
+- `openspec/changes/monthly-expense-tracker-v1/` - design/spec/task source for the product.
+
+## Key behavior to know
+
+- Dashboard aggregates all records, then filters them to the selected month in memory.
+- `getCurrentMonthKey()` uses local machine time.
+- `generateMonthlyInsight()` in `src/lib/insights.ts`:
+  - builds a structured prompt from dashboard totals, category breakdown, recent expenses, and chart points
+  - expects strict JSON with `summary` and `recommendations`
+  - falls back when activity is sparse or Ollama is unavailable
+  - stores the final result in `MonthlyInsight`
+- The fallback message is intentionally safe and short when data is too sparse.
+
+## Known gotchas
+
+- If dashboard values appear missing, confirm the selected month matches the seeded data.
+- If Docker backup fails, check `DATABASE_URL`; the backup route reads the SQLite path from the env var.
+- Prisma migration ordering matters because migration folders are applied lexicographically.
+- In Docker Compose on Linux, `extra_hosts: host-gateway` is needed for host Ollama access.
+
+## Current enhancement target
+
+- The next useful improvement is making the generated monthly summary more helpful and more structured.
+- Best place to change it: `src/lib/insights.ts`.
+- Likely changes:
+  - strengthen the prompt with clearer sections or required observations
+  - improve the fallback logic for sparse months
+  - optionally store more structured fields in `MonthlyInsight`
+  - update the dashboard card rendering in `src/components/home-dashboard.tsx` if the output shape changes
+
+## Useful commands
+
+```bash
+npm run dev
+npx prisma migrate deploy
+npx prisma db seed
+npm test
+```
+
+If you need to verify the dashboard API directly:
+
+```bash
+curl "http://localhost:3000/dashboard?month=2026-03"
+```
+
+## Recommended next step for another agent
+
+1. Read `src/lib/insights.ts`, `src/lib/dashboard.ts`, and `prisma/schema.prisma`.
+2. Decide whether to improve the insight prompt, the stored data shape, or the dashboard rendering.
+3. Make the change, then verify with the dashboard API and a generated insight.

+## Context
+
+The project uses Next.js with Tailwind CSS v4 and a warm stone/amber palette. All styling is done via Tailwind utility classes directly in JSX. There are no separate CSS modules for components. The root layout owns the `<html>` and `<body>` tags, making it the natural place to manage the theme class and prevent flash-of-unstyled-content.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Implement class-based dark mode that works with Tailwind v4's `@custom-variant` API.
+- Prevent theme flash on page load with an inline blocking script.
+- Persist user preference in `localStorage` under the key `theme`.
+- Fall back to system preference (`prefers-color-scheme`) when no preference is saved.
+- Keep the dark palette warm and consistent with the existing amber/stone design language.
+
+**Non-Goals:**
+- Server-side theme rendering or cookies (local-only app, no SSR theme concerns beyond flash prevention).
+- Per-page or per-component theme overrides.
+- Animated theme transitions beyond the existing `transition-duration: 180ms` on interactive elements.
+
+## Decisions
+
+### Use Tailwind v4 `@custom-variant` for class-based dark mode
+- Rationale: Tailwind v4's default dark mode is media-query-based. Adding `@custom-variant dark (&:where(.dark, .dark *))` in `globals.css` enables the `dark:` prefix to respond to a class on any ancestor, which is the standard pattern for toggle-able dark mode.
+- Alternative considered: Continue using media-query dark mode with no toggle. Rejected because users cannot override system preference.
+
+### Store theme preference in `localStorage`
+- Rationale: Simple, synchronous, requires no server or cookies. Reads correctly in the blocking inline script.
+- Alternative considered: Cookies for SSR. Rejected because this app is local-first and has no meaningful SSR theme benefit.
+
+### Inject an inline blocking script in `<head>` to set the `dark` class before first paint
+- Rationale: Prevents the flash where the page briefly renders in light mode before React hydrates and reads `localStorage`. The script is small and runs synchronously.
+- Alternative considered: Set the class in a React `useEffect`. Rejected because `useEffect` runs after paint, causing a visible flash.
+
+### Warm deep-stone dark palette
+- Rationale: The light theme is built on warm stone and amber tones. The dark theme mirrors this with deep stone backgrounds (`stone-950`, `stone-900`, `stone-800`) and dimmed amber/emerald accents, keeping the visual identity coherent.
+- Alternative considered: Neutral dark greys. Rejected because they clash with the warm amber accents and feel disconnected from the brand.
+
+## Risks / Trade-offs
+
+- [Inline script adds a small amount of render-blocking HTML] → Acceptable; the script is under 200 bytes and only runs once per page load.
+- [LocalStorage is unavailable in some privacy modes] → The script wraps the read in a try/catch and falls back to system preference.
+- [Many components have hardcoded warm background strings like `bg-[#fffaf2]`] → These are replaced with equivalent Tailwind tokens plus `dark:` overrides so the mapping is explicit and maintainable.
+
+## Migration Plan
+
+1. Update `globals.css` with `@custom-variant dark` and dark-mode CSS variable overrides.
+2. Create the `ThemeToggle` client component.
+3. Update `layout.tsx` to add the blocking script and render `ThemeToggle` in the header.
+4. Update `site-nav.tsx` with dark-mode nav styles.
+5. Update `home-dashboard.tsx`, `expense-workspace.tsx`, `paycheck-workspace.tsx`, and `recurring-expense-manager.tsx` with `dark:` variants.
+6. Update page-level header text that uses hardcoded colour classes.
+
+## Open Questions
+
+- Should the toggle also expose a "System" option (three-way: Light / Dark / System) rather than a binary flip? Deferred to a follow-up; the initialisation script already handles system fallback on first visit.

+## Why
+
+The app currently ships with a warm light theme only. Adding a system-aware dark mode with a manual toggle removes eye strain in low-light conditions and meets baseline accessibility expectations for a personal finance tool used at any hour.
+
+## What Changes
+
+- Add a class-based dark mode variant using Tailwind v4 `@custom-variant` so all `dark:` utilities are controlled by a `dark` class on `<html>`.
+- Add a `ThemeToggle` component that persists the user's preference in `localStorage` and initialises the correct class before first paint to prevent flash.
+- Update the root layout to inject the inline initialisation script and render the toggle inside the existing header.
+- Apply `dark:` variants to all UI components to produce a warm, deep-stone dark palette consistent with the existing amber/stone design language.
+
+## Capabilities
+
+### New Capabilities
+- `dark-mode`: Users can switch between light and dark themes with a toggle that persists across sessions. System preference is respected on first visit.
+
+### Modified Capabilities
+- `expense-tracking`: Expense workspace and recurring expense manager now render correctly in both themes.
+- `paycheck-tracking`: Paycheck workspace now renders correctly in both themes.
+- `monthly-dashboard`: Dashboard sections, insight cards, category bars, and stat cards now render correctly in both themes.
+
+## Impact
+
+- Affected code: `globals.css`, `layout.tsx`, all components under `src/components/`, and page header text in `src/app/`.
+- APIs: None.
+- Dependencies: None — uses Tailwind v4 built-ins and the Web Storage API.
+- Systems: No server-side changes required; theme state is fully client-side.
