+# Changelog
+
+## 0.1.0 - 2026-03-25
+- Created initial frontend-only React + TypeScript project scaffold with Vite.
+- Added typed Marathon API client for fetching/searching items from `/api/items/all`.
+- Implemented initial app features:
+  - Item search by name.
+  - Top 5 relevant search results with icons.
+  - Click-to-add items into to-do list.
+  - Quantity editing per item.
+  - Completed state toggle.
+  - Item deletion.
+- Added simple, minimal UI styling.
+- Added `README.md` documentation and local setup instructions.
+
+## 0.2.0 - 2026-03-25
+- Fetched faction upgrades data from `https://marathondb.gg/js/data/faction-upgrades.js` and added it to app data sources.
+- Extended search results with faction upgrades that include salvage requirements in their levels.
+- Added upgrade click behavior: clicking an upgrade adds all mapped salvage items to the to-do list and increases quantity when an item already exists.
+- Added image URL fallback candidates for search/list icons with extension order ending in `.webp`.
+
+## 0.3.0 - 2026-03-25
+- Added a local proxy server (`proxy/server.js`) using Node + SQLite (`proxy/catalog.db`).
+- Proxy now fetches Marathon items and faction upgrades from source URLs, builds a combined searchable catalog, and serves it at `GET /api/catalog`.
+- Added automatic catalog refresh every 24 hours and a manual refresh endpoint `POST /api/catalog/refresh`.
+- Frontend data loading now uses `/api/catalog` instead of hitting external source endpoints directly.
+- Added Vite dev proxy configuration for `/api` and `/health` to `http://localhost:8787`.
+- Added a right-side faction upgrade tag in search results, using faction color and `<faction name> upgrade` label text.
+- Added temporary faction-color highlight animation on affected to-do items when clicking an upgrade search result.
+
+## 0.4.0 - 2026-03-25
+- Reorganized repository into explicit `frontend/` and `backend/` directories.
+- Moved React app files to `frontend/` and proxy API to `backend/server.js`.
+- Moved SQLite catalog storage path to `backend/data/catalog.db`.
+- Added `backend/references/` for source reference files (`api.js`, faction upgrades snapshots).
+- Updated scripts/config/docs for the new structure (`dev:frontend`, `dev:backend`, Vite root set to `frontend`).
+- Added `dev:all` script to start backend and frontend together with one command.
+- Replaced inline `dev:all` command with `scripts/dev-all.mjs` for reliable Windows process spawning.
+- Upgrade search results now use faction assets from `backend/data/faction-assets/*.png` via `/api/faction-assets/:file`.
+- Upgrade search result rows now have border color based on faction color.
+- Upgrade search results now expose per-level salvage and require clicking a level button (`L1`, `L2`, ...) to add items.
+- Faction-color border is now applied around the upgrade icon frame (not the whole search row).

+# marathon.todo
+
+A frontend-only React + TypeScript app for planning what to loot (or do) in raid in Bungie's Marathon.
+
+## Features
+- Search for Marathon items by name.
+- Show up to 5 relevant results with item icons.
+- Search also includes faction upgrades with salvage requirements.
+- Add an item to a to-do list by clicking a search result.
+- Clicking an upgrade search result adds all mapped salvage materials to the to-do list.
+- Set quantity per to-do entry.
+- Mark entries completed.
+- Delete entries.
+- Persist to-do entries in browser `localStorage`.
+
+## Data Source
+- Frontend fetches a local proxy endpoint: `/api/catalog`
+- Proxy source data:
+  - Items: `https://items.marathondb.gg/api/items`
+  - Faction upgrades: `https://marathondb.gg/js/data/faction-upgrades.js`
+- Proxy stores processed catalog in SQLite (`backend/data/catalog.db`) and refreshes every 24h.
+
+## Project Structure
+- `frontend/`: Vite + React app (`frontend/src`, `frontend/index.html`)
+- `backend/`: local proxy API (`backend/server.js`) and SQLite data (`backend/data/`)
+- `backend/references/`: downloaded reference source files used during development
+
+## Tech Stack
+- React
+- TypeScript
+- Vite
+
+## Run Locally
+1. Install dependencies:
+   ```bash
+   npm install
+   ```
+2. Start backend + frontend together:
+   ```bash
+   npm run dev:all
+   ```
+3. Or run separately if preferred:
+   ```bash
+   npm run dev:backend
+   npm run dev:frontend
+   ```
+4. Build production assets:
+   ```bash
+   npm run build
+   ```

+# marathon.todo
+
+A web application that allows users to create a to-do list of what to loot (or do) in raid in Bungie's Marathon video game.
+
+## Tech Stack
+- React
+- TypeScript
+- Frontend-only
+
+## Data Source
+https://marathondb.gg/ provides a public API with all the necessary game data.
+
+The `app.js` file downloaded from this site can be used to generate a TypeScript client for the API.
+
+## Project Rules
+- Save all added features and changes (except very minor ones) to the `CHANGELOG.md` file.
+- Always update the `README.md` file accordingly.
+
+## Initial Features
+- User can search for an item by name.
+- Search results display up to 5 relevant items with their icons.
+- User can add an item to the to-do list by clicking on it.
+- User can specify the quantity for each added item.
+- User can mark items as completed.
+- User can delete items from the to-do list.
+
+## UI
+- Keep the UI very simple for now.
+- Minimal styling.
