update: workflow and css

- Add ARCHITECTURE.md with full system overview (data flow, modules, build)
- Add AGENTS.md as a guide for future AI agents working on this project
- Split monolithic styles.css into focused files under assets/:
  variables, animations, layout, navbar, header, cards, config,
  filters, utils, greet
- Fix justfile: replace `cargo run tauri dev/build` with `cargo tauri dev/build`

+# Agent Guide: marstemedia
+
+This document is for AI agents working on this codebase. Read it before touching anything.
+
+---
+
+## What is this project?
+
+**marstemedia** is a cross-platform desktop (+ Android) news reader app built with:
+- **Tauri v2** as the native shell
+- **Yew** (Rust → WebAssembly) for the UI
+- **Rust** for all backend logic (networking, file I/O, cryptography)
+
+It has three features:
+1. **Nostr feed** — anonymous browsing of decentralized social posts, filterable by hashtag
+2. **RSS reader** — fetches and displays articles from a user-configurable list of RSS/Atom feeds
+3. **AI news** — one-click tech news summary from Groq (Llama 3) or OpenRouter
+

+
+## How to Add a New Page
+
+1. Create `src/pages/yourpage.rs` as a Yew `#[function_component]`.
+2. Export it in `src/pages/mod.rs`: `pub mod yourpage;`
+3. Add a variant to the `Route` enum in `src/app.rs`:
+   ```rust
+   #[at("/yourpage")]
+   YourPage,
+   ```
+4. Add a match arm in the `switch` function in `src/app.rs`:
+   ```rust
+   Route::YourPage => html! { <YourPage /> },
+   ```
+5. Add a `<Link<Route>>` in `src/navbar/navbar.rs`.
+
+---
+
+## How to Add a New Backend Command
+
+1. Write your async function in the appropriate module (`src-tauri/src/home.rs`, `news.rs`, or a new file).
+2. Annotate it with `#[tauri::command]`.
+3. If you need shared state, add a field to `NewsState` in `src-tauri/src/news.rs`, or create a new state struct and call `.manage()` in `lib.rs`.
+4. Register the command in `src-tauri/src/lib.rs` inside `tauri::generate_handler![...]`.
+5. In the frontend, call it with `invoke("your_command_name", args)`.
+
+---
+
+## How to Call a Backend Command from the Frontend
+
+Every page that needs backend calls declares this extern at the top:
+
+```rust
+#[wasm_bindgen]
+extern "C" {
+    #[wasm_bindgen(js_namespace = ["window", "__TAURI__", "core"], catch)]
+    async fn invoke(cmd: &str, args: JsValue) -> Result<JsValue, JsValue>;
+}
+```
+
+Serialize args with `serde_wasm_bindgen::to_value(...)`, deserialize results with `serde_wasm_bindgen::from_value(...)`. Use `spawn_local` to run async calls inside Yew callbacks.
+
+---
+
+## Key Patterns to Know
+
+### State management (frontend)
+Yew uses `use_state` hooks. There is no global store — state lives inside components. If two pages need to share data, consider lifting state to `app.rs` or using Tauri's managed state on the backend.
+
+### State management (backend)
+`NewsState` in `src-tauri/src/news.rs` is registered with `.manage()` and injected into commands via `State<'_, NewsState>`. All fields are `Mutex<T>` — always lock, read/write, and drop the lock quickly. **API keys are in-memory only** (not saved to disk).
+
+### Config persistence
+RSS feeds are saved to `<app_config_dir>/rss.ron` using the `ron` crate. Access the config path via `app.path().app_config_dir()`. Pattern is: read on load, write on save, keep in-memory state in sync.
+
+### Markdown rendering
+The `News` page renders article content as Markdown using `pulldown-cmark`. The output is injected with `Html::from_html_unchecked`. Only use this for content you control or have sanitized.
+
+### Privacy pattern (Nostr)
+A new random keypair is generated on every `fetch_nostr_posts` call. This is intentional — do not change this to a persistent key without understanding the privacy implications.
+
+---
+
+## CSS
+
+`styles.css` in the project root is the single entry point — it only contains `@import` statements. All actual styles are split into files under `assets/`:
+
+| File | What's inside |
+|---|---|
+| `assets/variables.css` | CSS custom properties (colors, fonts), reset, `body`/`html` |
+| `assets/layout.css` | `.feed-container`, responsive media queries |
+| `assets/navbar.css` | `.navbar-dock`, `.nav-link` |
+| `assets/header.css` | `.feed-header`, `.mode-toggle`, `.toggle-btn`, `.action-btn`, `.provider-switch` |
+| `assets/cards.css` | `.post-card`, `.markdown-body`, `.post-category-badge` |
+| `assets/config.css` | `.config-panel`, RSS list, inputs, `.add-btn`, `.delete-btn`, `.save-master-btn` |
+| `assets/filters.css` | Hashtag chips (Home), `.category-bar`, `.cat-btn` (News) |
+| `assets/animations.css` | `@keyframes float`, `slideIn`, `pulse-subtle` |
+| `assets/utils.css` | `.reload-btn-large`, `.error-box`, `.loading-spinner`, `.status-msg` |
+| `assets/greet.css` | `.robot-container`, `.robot-icon`, `.bubble` |
+
+When adding styles for a new page, create a new file in `assets/` and add an `@import` line to `styles.css`. There is no CSS framework — vanilla CSS with custom classes.
+
+---
+
+## Build & Dev
+
+```bash
+# Start dev server (hot reload)
+cargo tauri dev
+
+# Build for desktop release
+cargo tauri build
+
+# Build for Android (requires Android SDK + NDK)
+cargo tauri android build
+
+# Frontend only (no Tauri shell)
+trunk serve
+```
+
+The `justfile` may contain additional shortcuts — check it first.
+
+---
+
+## Dependencies Worth Knowing
+
+| Crate | Used for |
+|---|---|
+| `yew` | UI components |
+| `yew-router` | Client-side routing |
+| `wasm-bindgen` / `wasm-bindgen-futures` | Wasm ↔ JS bridge |
+| `serde-wasm-bindgen` | Serialize/deserialize across the Tauri IPC |
+| `pulldown-cmark` | Markdown → HTML in the frontend |
+| `nostr-sdk` | Nostr protocol (via `easy-nostr` wrapper) |
+| `reqwest` | HTTP client (rustls, no OpenSSL) |
+| `feed-rs` | RSS/Atom feed parsing |
+| `ron` | Config file serialization |
+| `tauri-plugin-opener` | Open URLs in system browser |
+
+---
+
+## What to Watch Out For
+
+- **`easy-nostr`** is a local path dependency at `src-tauri/easy-nostr/`. It is also a private Git repo cloned by CI. If you need to update it, clone it manually into that path.
+- **No OpenSSL** — both `reqwest` usages (frontend and backend) use `rustls-tls` with `default-features = false`. Keep it that way to avoid cross-compilation pain on Android/CI.
+- **`wasm32-unknown-unknown`** target is required for the frontend. `aarch64-linux-android` and friends are required for Android CI.
+- The `Greet` page (`src/pages/greet.rs`) appears to be a leftover demo page from the Tauri template. It is still linked in the navbar — decide whether to keep or remove it.
+- API keys entered by the user are held in `Mutex<String>` fields in `NewsState`. They are lost when the app restarts. There is no persistence for keys by design.

+# Architecture: marstemedia
+
+marstemedia is a desktop (and Android) application built with **Tauri v2**. The UI is written in Rust compiled to WebAssembly using **Yew**, and the backend logic runs as native Rust code inside the Tauri host process.

+         ▲  renders inside a webview (WebKit/Edge)
+```
+
+The frontend never touches the network directly for heavy operations — it sends named commands via `window.__TAURI__.core.invoke()` to the backend, which does the actual networking, file I/O, and cryptography.
+
+---
+
+## Frontend (`src/`)
+
+Built with **Yew 0.21** (React-style component model for Rust/Wasm) and **yew-router** for client-side routing.
+
+### Entry point
+
+| File | Role |
+|---|---|
+| `src/main.rs` | Bootstraps the Wasm app, mounts the `App` component |
+| `src/app.rs` | Defines the `Route` enum and the top-level layout (router + navbar) |
+
+### Routes
+
+| Path | Component | File |
+|---|---|---|
+| `/` | `Home` | `src/pages/home.rs` |
+| `/news` | `News` | `src/pages/news.rs` |
+| `/greet` | `Greet` | `src/pages/greet.rs` |
+
+### Components
+
+- **`Navbar`** (`src/navbar/navbar.rs`) — Fixed bottom dock with links to all three routes. Reads the current route via `use_route` to highlight the active link.
+- **`Home`** (`src/pages/home.rs`) — Nostr feed. Manages hashtag filter state, invokes `fetch_nostr_posts` on load and on user interaction, renders posts as `PostCard` components.
+- **`News`** (`src/pages/news.rs`) — Dual-mode news page. Toggles between AI mode (Groq / OpenRouter) and RSS mode. Has a collapsible config panel for API keys and RSS feed management. Renders articles as `NewsCard` with Markdown support via `pulldown-cmark`.
+
+### How the frontend talks to the backend
+
+Every backend call uses the `invoke` wasm-bindgen extern:
+
+```rust
+#[wasm_bindgen(js_namespace = ["window", "__TAURI__", "core"], catch)]
+async fn invoke(cmd: &str, args: JsValue) -> Result<JsValue, JsValue>;
+```
+
+Arguments are serialized with `serde-wasm-bindgen` and results are deserialized back into typed Rust structs.
+
+---
+
+## Backend (`src-tauri/src/`)
+
+Native Rust code that runs in the Tauri host process. Registered commands are the only API surface the frontend can call.
+
+### Entry point
+
+| File | Role |
+|---|---|
+| `src-tauri/src/main.rs` | Desktop executable entry point, calls `run()` |
+| `src-tauri/src/lib.rs` | Configures Tauri: registers `NewsState`, registers all commands |
+
+### Modules
+
+#### `home.rs` — Nostr
+
+Handles the `fetch_nostr_posts` command.
+
+1. Generates a fresh, random throwaway keypair on every call (privacy by design — no persistent identity).
+2. Creates an `EasyNostr` client using the temp key (via the local `easy-nostr` library).
+3. Connects to three relays: `relay.damus.io`, `nos.lol`, `relay.snort.social`.
+4. Fetches posts by hashtag list, or random posts if no tags are given.
+5. Maps results to the serializable `LocalPost` struct and returns JSON.
+
+#### `news.rs` — RSS & AI News
+
+Manages `NewsState` (held in Tauri's managed state, shared across calls):
+
+```
+NewsState {
+    openrouter_key: Mutex<String>
+    groq_key:       Mutex<String>
+    rss_config:     Mutex<RssConfig>
+}
+```
+
+**Commands:**
+
+| Command | What it does |
+|---|---|
+| `load_rss_config` | Reads `rss.ron` from the app config dir; writes 16 default feeds if the file is missing or has fewer than 3 entries |
+| `save_rss_urls` | Serializes the feed list to `rss.ron` and updates in-memory state |
+| `save_openrouter_key` | Stores the key in `NewsState.openrouter_key` (in-memory only, not persisted to disk) |
+| `save_groq_key` | Same for the Groq key |
+| `fetch_ai_news` | POSTs to Groq or OpenRouter chat completions API; asks for a short tech news summary in German Markdown |
+| `fetch_rss_news` | Iterates the in-memory feed list, fetches each feed with `reqwest`, parses with `feed-rs`, takes up to 3 articles per feed, returns `Vec<NewsArticle>` |
+
+### Local library: `easy-nostr`
+
+Located at `src-tauri/easy-nostr/` (path dependency). Wraps `nostr-sdk` to provide high-level helpers like `get_random_posts()` and `get_posts_by_hashtags()`. Written by the same author (Bytemalte).
+
+---
+
+## Configuration & Persistence
+
+| What | Where | Format |
+|---|---|---|
+| RSS feed list | `<app_config_dir>/rss.ron` | RON |
+| API keys | In-memory (`NewsState`) — lost on restart | — |
+| App window config | `src-tauri/tauri.conf.json` | JSON |
+
+API keys are intentionally not persisted to disk. The user re-enters them each session via the config panel.
+
+---
+
+## Build System
+
+| Tool | Role |
+|---|---|
+| `trunk` | Builds and bundles the Yew/Wasm frontend (`trunk build` / `trunk serve`) |
+| `tauri-cli` | Wraps the full build and produces the native app bundle |
+| `Trunk.toml` | Trunk configuration (output dir `dist/`, used by Tauri) |
+| `justfile` | Developer shortcuts |
+
+The `tauri.conf.json` wires them together:
+```
+beforeDevCommand:   trunk serve      (starts dev server on :1420)
+beforeBuildCommand: trunk build      (builds Wasm)
+frontendDist:       ../dist          (Tauri embeds this)
+```
+
+### CI / Android
+
+`.gitea/workflows/android.yaml` runs on push to `main` or version tags. It:
+1. Clones `easy-nostr` as a private submodule.
+2. Installs Rust with four Android targets + `wasm32-unknown-unknown`.
+3. Installs Trunk (binary) and `tauri-cli` (cargo).
+4. Sets up Android SDK + NDK 25.
+5. Runs `cargo tauri android build`.
