Redesign frontend UI with Observatory theme

New teal-accent color system, DM Sans + JetBrains Mono typography,
glow effects, animated gradient login page, animated dashboard counters
with gradient-border stat cards, event timeline, sidebar with active
glow indicators, and polished components (modals, cards, snackbar).

 The README is the primary user-facing documentation and must accurately reflect the current state of the integration.

+## Development Servers

+**IMPORTANT**: When the user requests it OR when backend code changes are made (files in `packages/server/`), you MUST restart the standalone server using this one-liner:
+```bash
+PID=$(netstat -ano 2>/dev/null | grep ':8420.*LISTENING' | awk '{print $5}' | head -1) && [ -n "$PID" ] && taskkill //F //PID $PID 2>/dev/null; sleep 1 && cd packages/server && pip install -e . 2>&1 | tail -1 && cd ../.. && IMMICH_WATCHER_DATA_DIR=./test-data IMMICH_WATCHER_SECRET_KEY=test-secret-key-minimum-32chars nohup python -m uvicorn immich_watcher_server.main:app --host 0.0.0.0 --port 8420 > /dev/null 2>&1 & sleep 3 && curl -s http://localhost:8420/api/health
+```
+
+**IMPORTANT**: Overlays (modals, dropdowns, pickers) MUST use `position: fixed` with inline styles and `z-index: 9999`. Tailwind CSS v4 `fixed`/`absolute` classes do NOT work reliably inside flex/overflow containers in this project. Always calculate position from `getBoundingClientRect()` for dropdowns, or use `top:0;left:0;right:0;bottom:0` for full-screen backdrops.
+
+**IMPORTANT**: When the user requests it, restart the frontend dev server using this one-liner:
+```bash
+PID=$(netstat -ano 2>/dev/null | grep ':5173.*LISTENING' | awk '{print $5}' | head -1) && [ -n "$PID" ] && taskkill //F //PID $PID 2>/dev/null; sleep 1 && cd frontend && npx vite dev --port 5173 --host > /dev/null 2>&1 & sleep 4 && curl -s -o /dev/null -w "Frontend: %{http_code}" http://localhost:5173/

+## Frontend Architecture Notes
+
+- **i18n**: Uses `$state` rune in `.svelte.ts` file (`lib/i18n/index.svelte.ts` or `index.ts` with auto-detect). Locale auto-detects from localStorage at module load time. `t()` is reactive via `$state`. `setLocale()` updates immediately without page reload.
+- **Svelte 5 runes**: `$state` only works in `.svelte` and `.svelte.ts` files. Regular `.ts` files cannot use runes -- use plain variables instead.
+- **Static adapter**: Frontend uses `@sveltejs/adapter-static` with SPA fallback. API calls proxied via Vite dev server config.
+- **Auth flow**: After login/setup, use `window.location.href = '/'` (hard redirect), NOT `goto('/')` (races with layout auth check).
+- **Tailwind CSS v4**: Uses `@theme` directive in `app.css` for CSS variables. Grid/flex classes work but `fixed`/`absolute` positioning requires inline styles in overlay components.
+
+## Backend Architecture Notes
+
+- **SQLAlchemy async + aiohttp**: Cannot nest `async with aiohttp.ClientSession()` inside a route that has an active SQLAlchemy async session -- greenlet context breaks. Eagerly load all DB data before entering aiohttp context, or use `check_tracker_with_session()` pattern.
+- **Jinja2 SandboxedEnvironment**: All template rendering MUST use `from jinja2.sandbox import SandboxedEnvironment` (not `jinja2.sandbox.SandboxedEnvironment` -- dotted access doesn't work).
+- **System-owned entities**: `user_id=0` means system-owned (e.g. default templates). Access checks must allow `user_id == 0` in `_get()` helpers.
+- **Default templates**: Stored as `.jinja2` files in `packages/server/src/immich_watcher_server/templates/{en,ru}/`. Loaded by `load_default_templates(locale)` and seeded to DB on first startup if no templates exist.
+- **FastAPI route ordering**: Static path routes (e.g. `/variables`) MUST be registered BEFORE parameterized routes (e.g. `/{config_id}`) to avoid path conflicts.
+- **`__pycache__`**: Add to `.gitignore`. Never commit.

+
+Everything you need to build a Svelte project, powered by [`sv`](https://github.com/sveltejs/cli).
+
+## Creating a project
+
+If you're seeing this, you've probably already done this step. Congrats!
+
+```sh
+# create a new project
+npx sv create my-app
+```
+
+To recreate this project with the same configuration:
+
+```sh
+# recreate this project
+npx sv@0.12.8 create --template minimal --types ts --no-install frontend
+```
+
+## Developing
+
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+
+```sh
+npm run dev
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
+```
+
+## Building
+
+To create a production version of your app:
+
+```sh
+npm run build
+```
+
+You can preview the production build with `npm run preview`.
+
+> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.
