+# Bundle Size Budget
+
+> **Target device**: Low-bandwidth mobile (≈ 300 kbps downlink, mid-range Android)
+> **Measurement tool**: `npm run analyze` → opens `@next/bundle-analyzer` treemap in browser
+> **Reported metric**: Next.js **First Load JS** per route (shown in `next build` output)
+
+---
+
+## How to measure
+
+```bash
+# 1. Run the analyzer (opens treemap in browser)
+npm run analyze
+
+# 2. Capture the per-route First Load JS sizes printed by `next build`
+npm run build
+```
+
+The `next build` stdout table ("Route (app)") is the source of truth for
+the numbers in this document. Copy the **First Load JS** column here after
+each significant PR that touches charts, animations, or large dependencies.
+
+---
+
+## Per-route JS budget
+
+| Route                   | Budget   | Baseline (pre-optimization) | Target (post-optimization) |
+| ----------------------- | -------- | --------------------------- | -------------------------- |
+| `/[locale]` (dashboard) | ≤ 200 kB | ~185 kB                     | ≤ 160 kB                   |
+| `/[locale]/analytics`   | ≤ 250 kB | ~310 kB (recharts eager)    | ≤ 200 kB                   |
+| `/[locale]/kingdom`     | ≤ 220 kB | ~280 kB (framer eager)      | ≤ 190 kB                   |
+| All other routes        | ≤ 180 kB | —                           | ≤ 180 kB                   |
+
+> **Budgets are enforced via code review**, not automated CI at this stage.
+> A follow-up issue should add `bundlesize` or a `next build` size assertion to CI.
+
+---
+
+## Lazy-loaded chunks (not in initial bundle)
+
+The following modules are split into async chunks and fetched only when the
+user navigates to the relevant route or triggers the relevant interaction:
+
+| Chunk / Module                  | Split at                          | Trigger                   |
+| ------------------------------- | --------------------------------- | ------------------------- |
+| `recharts` + chart components   | `FinancialPerformanceDashboard`   | `/analytics` page render  |
+| `framer-motion` runtime         | `XPGainAnimation`, `LevelUpModal` | First gamification event  |
+| `KingdomProgressWidget`         | `kingdom/page.tsx`                | `/kingdom` route render   |
+| `AchievementsPanel`             | `kingdom/page.tsx`                | `/kingdom` route render   |
+| `GamificationSettings`          | `kingdom/page.tsx`                | `/kingdom` route render   |
+| `FinancialPerformanceDashboard` | `analytics/page.tsx`              | `/analytics` route render |
+

+
+## Dependency sizes (uncompressed / gzip)
+
+Reference sizes from the `npm run analyze` treemap (update after major version bumps):
+
+| Package                 | Uncompressed | Notes                                                           |
+| ----------------------- | ------------ | --------------------------------------------------------------- |
+| `recharts`              | ~500 kB      | Area/Line/Bar charts. Split via `next/dynamic`.                 |
+| `framer-motion`         | ~120 kB      | Animation runtime. Split via `next/dynamic`.                    |
+| `lottie-react`          | ~220 kB      | Not currently used in any component. Remove if unused after V2. |
+| `@stellar/stellar-sdk`  | ~300 kB      | Required for wallet. Cannot be split further.                   |
+| `@tanstack/react-query` | ~35 kB       | Low impact.                                                     |
+| `zustand`               | ~5 kB        | Low impact.                                                     |

+## Before/After: First Load JS (estimated)
+
+> These are engineering estimates. Replace with real `next build` output numbers
+> after the optimization PR lands and the project builds successfully.
+
+### `/[locale]/analytics`
+
+| State                    | First Load JS | Delta       |
+| ------------------------ | ------------- | ----------- |
+| Before (recharts eager)  | ~310 kB       | baseline    |
+| After (recharts dynamic) | ~190 kB       | **−120 kB** |
+
+### `/[locale]/kingdom`
+
+| State                                         | First Load JS | Delta       |
+| --------------------------------------------- | ------------- | ----------- |
+| Before (framer-motion eager in gamification)  | ~280 kB       | baseline    |
+| After (framer-motion dynamic in gamification) | ~170 kB       | **−110 kB** |
+
+### `/[locale]` (dashboard)
+
+| State                                           | First Load JS | Delta    |
+| ----------------------------------------------- | ------------- | -------- |
+| Before                                          | ~185 kB       | baseline |
+| After (no direct recharts/framer on this route) | ~185 kB       | ± 0      |

+
+## How to run the bundle analyzer
+
+```bash
+# Wire is: ANALYZE=true → next.config.ts → @next/bundle-analyzer
+npm run analyze
+
+# On Windows (PowerShell):
+$env:ANALYZE="true"; npm run build
+```
+
+The analyzer opens two HTML treemaps in your browser:
+
+- `client.html` — all client-side JS chunks
+- `server.html` — server-side JS chunks (usually less relevant)
+
+Look for large boxes inside your route chunks. Key suspects:
+
+- `recharts` inside any non-analytics route chunk
+- `framer-motion` inside the initial dashboard chunk
+- `lottie-react` if it appears at all (it is unused)
+
+---
+
+## Maintenance rules
+
+1. **After any PR that adds a new `import` of recharts, framer-motion, or lottie-react**:
+   run `npm run analyze` and confirm the import appears only inside the expected lazy chunk.
+
+2. **If First Load JS for any route exceeds its budget**:
+   open an issue tagged `perf` and block merge until resolved.
+
+3. **Update this table after every performance-impacting PR.**
