Add avatar upload to Settings, document Settings page, update README

- Profile section: click avatar to upload a personal photo (FileReader
  preview, hover camera icon overlay), replacing static initials
- README.md rewritten with project-specific page status table, dev
  setup, tech stack, and deployment notes
- design-decisions.md: add Settings Page subsection documenting layout,
  section-switching, and the avatar upload technique

-# React + TypeScript + Vite
+# ArchNest
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+A self-hosted ops dashboard — infrastructure monitoring, a bookmark hub for your homelab/cloud links, an embedded terminal, and system settings, all in one place.
 
-Currently, two official plugins are available:
+Built with React 19 + TypeScript + Vite, styled with Tailwind CSS v4, charts via Recharts, icons via Lucide React.

-## React Compiler
+| Page | Route | Status |
+|------|-------|--------|
+| Glance | `/` | Done — main ops dashboard (system status, resource overview, alerts, network traffic) |
+| Infrastructure | `/infrastructure` | Done — resource distribution, node status grid, cost/trend breakdown. "Network" sub-tab planned as a future addition. |
+| BookNest | `/booknest` | Done — categorized bookmark hub with quick access, favorites, link health, and category breakdown |
+| Terminal | `/terminal` | Pending — will be based on a fork of the (archived) Termix project, not yet merged in |
+| Settings | `/settings` | Done — Profile (incl. avatar upload), Appearance, Integrations, Notifications, Data & Backup, About |
 
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+See `archnest-blueprint.md` for the original per-page design spec and `design-decisions.md` for the visual/UX conventions and lessons learned while building each page — read that file before making layout changes, it documents *why* things are built the way they are (hero banner layering, card blend techniques, icon library gotchas, etc.).
 
-## Expanding the ESLint configuration
+## Development
 
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+```bash
-
+npm install
-```js
+npm run dev
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // Remove tseslint.configs.recommended and replace with this
-      tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      tseslint.configs.stylisticTypeChecked,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
 ```
 
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+Type-check with `npx tsc --noEmit` before committing — Vite/the browser surface some runtime errors (e.g. missing icon exports) that the type-checker won't catch, so also smoke-test pages in a browser.
 
-```js
+## Tech Stack
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'

+### Settings Page
+- No mockup image existed for this page — built directly from the blueprint's Page 6
+  spec rather than iterating against a screenshot.
+- Layout: fixed-width (200px) left nav listing the 6 sections (Profile, Appearance,
+  Integrations, Notifications, Data & Backup, About) + a scrollable content panel on
+  the right showing the active section. No hero banner (not in the blueprint spec for
+  this page, and a settings page doesn't need one).
+- Active section is local component state (a string id) mapped through a
+  `sectionComponents` record to the corresponding section-renderer function — simplest
+  approach for a page with no routing/deep-linking requirement.
+- Shared style helpers (`cardBase`, `sectionTitle`, `labelStyle`, `inputStyle`) plus two
+  small reusable components defined in the same file: `Toggle` (on/off pill switch) and
+  `GoldButton` (gold-filled primary / danger-outline variant) — kept local to
+  `Settings.tsx` rather than extracted, since no other page needs them yet.
+- **Integrations** cards mask secret fields (API keys/tokens) behind dots with an eye
+  icon to reveal/hide, plus a "Test Connection" button per card — matches the blueprint's
+  explicit "masked secrets with eye toggle" instruction.
+- **Avatar upload** (Profile section): the avatar circle is clickable and opens a hidden
+  `<input type="file" accept="image/*">` via a `useRef` + `.click()` call rather than a
+  visible file input — keeps the round avatar as the only visible control. On change,
+  `FileReader.readAsDataURL` converts the selected image to a base64 data URL stored in
+  component state, which becomes the circle's `backgroundImage` (cover-fit), replacing
+  the "AO" initials fallback. A hover-only camera-icon overlay (Tailwind `group` /
+  `group-hover:opacity-100`) signals the circle is clickable without cluttering the
+  default state. This is a frontend-only preview (no backend upload endpoint exists yet).
