+## Deployment Modes
+
+WeatherStar 4000+ supports two deployment modes:
+
+### Server Deployment (Recommended)
+
+* Includes Node.js server with caching proxy for better performance (especially when running on a local server for multiple clients)
+* Server-side request deduplication and caching
+* Weather API observability and logging
+* Used by: `npm start`, `DIST=1 npm start`, and `Dockerfile.server`
+
+### Static Deployment
+
+* Pure client-side deployment using nginx to serve static files
+* All API requests are made directly from each browser to the weather services
+* Browser-based caching
+* Used by: static file hosting and default `Dockerfile`
+
 ## Run Your WeatherStar
-To run via Node locally:
-```
+
+Ensure you have Node installed. Clone the repository:
+```bash
 git clone https://github.com/netbymatt/ws4kp.git
 cd ws4kp
-npm i
-node index.mjs
+npm install
 ```
 
-To run via Docker: 
+### Development Mode (individual JS files, easier debugging)
+```bash
+npm start
 ```
+
+### Development Mode without proxy caching
+```bash
+STATIC=1 npm start
+```
+
+### Production Mode (minified/concatenated JS, faster loading)
+```bash
+npm run build
+DIST=1 npm start
+```
+
+### Production Mode without proxy caching (simulates static Docker deployment)
+```bash
+npm run build
+STATIC=1 DIST=1 npm start
+```
+
+For all modes, access WeatherStar by going to: http://localhost:8080/
+
+### Key Differences
+
+**Development Mode (`npm start`):**
+- Uses individual JavaScript module files served directly
+- Easier debugging with source maps and readable code
+- Slower initial load (many HTTP requests for individual files)
+- Live file watching and faster development iteration
+
+**Production Mode (`DIST=1 npm start`):**
+- Uses minified and concatenated JavaScript bundles
+- Faster initial load (fewer HTTP requests, smaller file sizes)
+- Optimized for performance with multiple clients
+- Requires `npm run build` to generate optimized files
+
+### Docker Deployments
+
+To run via Docker using a "static deployment" where everything happens in the browser (no server component, like STATIC=1):
+
+```bash
 docker run -p 8080:8080 ghcr.io/netbymatt/ws4kp
 ```
-Open your web browser: http://localhost:8080/

+### Serving a static app
+
+There are several ways to deploy WeatherStar as a static app that runs entirely in the browser:
+
+**Manual static hosting (Apache, nginx, CDN, etc.):**
+Build static distribution files for upload to any web server:
+
+```bash
 npm run build
 ```
-The resulting files will be in the /dist folder in the root of the project. These can then be uploaded to a web server for hosting, no server-side scripting is required.
 
-When using the provided Docker image, the browser will generate `playlist.json`
-on the fly by scanning the `/music` directory served by nginx. The image
-intentionally omits this file so the page falls back to scanning the directory.
-Simply bind mount your music folder and the playlist will be created
-automatically. If no files are found in `/music`, the built in tracks located in
-`/music/default/` will be used instead.
+The resulting files in `/dist` can be uploaded to any web server; no server-side scripting is required.
 
-The nginx configuration also sets the `X-Weatherstar: true` header on all
-responses. This uses `add_header ... always` so the header is sent even for
-404 responses. When `playlist.json` returns a 404 with this header present, the
-browser falls back to scanning the `/music` directory. If you host the static
-files elsewhere, be sure to include this header so the playlist can be generated
-automatically.
+**Docker static deployment:**
+The default Docker image uses nginx to serve pre-built static files:
+
+```bash
+docker run -p 8080:8080 ghcr.io/netbymatt/ws4kp
+```
+
+**Node.js in static mode:**
+Use the Node.js server as a static file host without the caching proxy:
+
+```bash
+STATIC=1 npm start          # Use Express to serve development files
+STATIC=1 DIST=1 npm start   # Use Express to serve (minimized) production files

+
+**Speed:** Controls the playback speed multiplier of the displays, from "Very Fast" (1.5x) to "Very Slow" (0.5x) with "Normal" being 1x
+
+**Widescreen:** Stretches the background to 16:9 to avoid "pillarboxing" on modern displays
+
+**Kiosk:** Immediately activates kiosk mode, which hides all settings. Exit by refreshing the page or using `Ctrl-K`. (Kiosk mode is similar to clicking the "Fullscreen" icon, but scales to the current browser viewport instead of activating the browser's actual "Fullscreen" mode.)
+
+**Sticky Kiosk:** When enabled, stores the kiosk mode preference in local storage so the page automatically enters kiosk mode (maximizing the size of the main weather display without any settings) on subsequent visits. This feature is designed primarily for **iPhone and iPad users** who want to create a Home Screen app experience, since Mobile Safari doesn't support PWA installation via manifest.json or the Fullscreen API:
+
+**For iOS/iPadOS (Mobile Safari):**
+
+1. Tap the _Share_ icon and choose **Add to Home Screen**
+2. Adjust the name as desired and tap **Add**
+3. Launch the newly-created Home Screen shortcut
+4. Configure all settings
+5. Tap to enable **Sticky Kiosk**
+6. _Make sure everything is configured exactly like you want it!_
+7. Tap **Kiosk**
+
+**For Android and Desktop browsers:** The included `manifest.json` file enables PWA (Progressive Web App) installation. To get the best app-like experience:
+
+1. Configure all your settings first (ignore the "Kiosk" and "Sticky Kiosk" settings)
+2. Create a permalink using the "Copy Permalink" feature and manually add `&kiosk=true` to the end
+3. Open the edited permalink URL in your browser
+4. Look for browser prompts to "Install" or "Add to Home Screen" from the kiosk-enabled URL
+5. The PWA will launch directly into kiosk mode (without forcing kiosk mode when accessed from the browser)
+
+For temporary fullscreen during regular browsing, use the fullscreen button in the toolbar.
+
+**Important Notes:**
+
+* **iOS/iPadOS limitations**: Mobile Safari strips all URL parameters when adding to Home Screen and runs shortcuts in an isolated environment with separate storage from the main Safari app
+* After creating a Home Screen app on iOS or iPadOS and activating Kiosk mode, the only way to change settings is to delete the Home Screen shortcut and recreate it
+* In situations where you _can_ edit a shortcut's URL, you can forcibly remove a "sticky" kiosk setting by adding `&kiosk=false` to the URL (or simply press `Ctrl-K` to exit kiosk mode if a keyboard is available)
+
+**Scan Lines:** Enables a retro-style scan line effect
+
+**Scan Lines Style:** Override the "auto" setting in case you prefer a different scale factor than what the automatic heuristics select for your browser and display
+
+**Units:** Switches between US and metric units. (Note that some text-based products from the National Weather Service APIs contain embedded units that are not converted.)
+
+**Volume:** Controls the audio level when music is enabled
+
 ## Music
+
 The WeatherStar had wonderful background music from the smooth jazz and new age genres by artists of the time. Lists of the music that played are available by searching online, but it's all copyrighted music and would be difficult to provide as part of this repository.
 
 I've used AI tools to create WeatherStar-inspired music tracks that are unencumbered by copyright and are included in this repo. To keep the size down, I've only included 4 tracks. Additional tracks are in a companion repository [ws4kp-music](https://github.com/netbymatt/ws4kp-music).

 If you're looking for the original music that played during forecasts [TWCClassics](https://twcclassics.com/audio/) has thorough documentation of playlists.
 
 ### Customizing the music
-Placing .mp3 files in the `/server/music` folder will override the default music included in the repo. Subdirectories will not be scanned. When weatherstar loads in the browser it will load a list if available files and randomize the order when it starts playing. On each loop through the available tracks the order will again be shuffled. If you're using the static files method to host your WeatherStar music is located in `/music`.
 
-If using Docker, you can bind mount a local folder containing your music files.
-Mount the folder at `/usr/share/nginx/html/music` so the browser can read the
-directory listing and build the playlist automatically. If there are no `.mp3`
-files in `/music`, the built in tracks from `/music/default/` are used.
+WeatherStar 4000+ supports background music during forecast playback. The music behavior depends on how you deploy the application:
+
+#### Express server modes (`npm start`, `DIST=1 npm start`, or `Dockerfile.server`)
+
+When running with Node.js, the server generates a `playlist.json` file by scanning the `./server/music` directory for `.mp3` files. If no files are found in `./server/music`, it falls back to scanning `./server/music/default/`. The playlist is served dynamically at the `/playlist.json` endpoint.
+
+**Adding your own music:** Place `.mp3` files in `./server/music/`
+
+**Docker server example:**
+```bash
+docker build -f Dockerfile.server -t ws4kp-server .
+docker run -p 8080:8080 -v /path/to/local/music:/app/server/music ws4kp-server
 ```
+
+#### Static hosting modes (default `Dockerfile`, nginx, Apache, etc.)
+
+When hosting static files, there are two scenarios:
+
+**Static Docker deployment:** The build process creates a `playlist.json` file with default tracks, but the Docker image _intentionally_ removes it to force browser-based directory scanning. The browser attempts to fetch `playlist.json`, receives a 404 response with the `X-Weatherstar` header, which causes it to  fallback to scanning the `music/` directory.
+
+**Manual static hosting:** If you build and upload the files yourself (`npm run build`), `playlist.json` will contain the default tracks unless you customize `./server/music/` before building.
+
+For directory scanning to work properly:
+* Your web server must generate directory listings for the `music/` path
+* Your web server must set the `X-Weatherstar: true` header (the provided nginx configuration does this)
+
+**Adding your own music:** Place `.mp3` files in `music/` (or bind mount to `/usr/share/nginx/html/music` for Docker)
+
+**Docker static example:**
+```bash
 docker run -p 8080:8080 -v /path/to/local/music:/usr/share/nginx/html/music ghcr.io/netbymatt/ws4kp
 ```
 
+Subdirectories will not be scanned. When WeatherStar loads in the browser, it randomizes the track order and reshuffles on each loop through the playlist.
+
 ### Music doesn't auto play
 Ws4kp is muted by default, but if it was unmuted on the last visit it is coded to try and auto play music on subsequent visits. But, it's considered bad form to have a web site play music automatically on load, and I fully agree with this. [Chrome](https://developer.chrome.com/blog/autoplay/#media_engagement_index) and [Firefox](https://hacks.mozilla.org/2019/02/firefox-66-to-block-automatically-playing-audible-video-and-audio/) have extensive details on how and when auto play is allowed.

+ * HTTP cache implementation for API proxy that respects cache-control headers
+ * (without external dependencies)
+ *
+ * Features:
+ * - Respects HTTP cache-control headers (s-maxage, max-age)
+ * - Heuristic caching based on Last-Modified headers when no explicit cache directives exist
+ * - Conditional requests using ETags and If-Modified-Since headers to validate stale content
+ * - In-flight request deduplication to prevent multiple simultaneous requests for the same resource
+ * - Comprehensive logging with cache hit/miss statistics and timing information
+ * - Timeout handling and error recovery mechanisms
+ *
+ * The cache uses a three-state system:
+ * - 'fresh': Content is within its TTL and served immediately
+ * - 'stale': Content has expired but can be revalidated with conditional requests (304 Not Modified)
+ * - 'miss': No cached content exists
+ *
+ * @class HttpCache
