 # VR Web Player
-A CDN-friendly web player for side-by-side stereoscopic video.
+A CDN-friendly web player for side-by-side stereoscopic video and still images.
 
 The player supports two projection modes:
 
 - `vr180`: an immersive 180 degree stereoscopic hemisphere in WebXR, with a draggable rectilinear fallback on non-XR browsers.
-- `plane`: a flat stereoscopic video plane in WebXR, with a normal flat left-eye fallback on non-XR browsers.
+- `plane`: a flat stereoscopic media plane in WebXR, with a normal flat left-eye fallback on non-XR browsers.
 
 ## How to use it
 Build the player first, then host the generated `vr180player/` directory on your CDN and include the module script. The script automatically loads its matching CSS file from the same folder, and it imports its helper modules with relative module paths.
 
-```html
-<div data-vr-web-player data-projection="vr180">
-	<video poster="poster.jpg" title="Demo Video" crossorigin="anonymous" playsinline preload="metadata">
-		<source src="sbs-video.mp4" type="video/mp4">
-	</video>
-</div>
-
-<script type="module" src="https://cdn.example.com/vr180player/vr180-player.js"></script>
-```
-
-Use `data-projection="plane"` for flat 3D video on a rectangular plane:
+Current F40 Pages CDN entrypoint:
 
 ```html
-<div data-vr-web-player data-projection="plane">
-	<video poster="poster.jpg" title="Demo Video" crossorigin="anonymous" playsinline preload="metadata">
-		<source src="sbs-video.mp4" type="video/mp4">
-	</video>
-</div>
+<script type="module" src="https://pages.f-40.com/VR-Web-Player/vr180player/vr180-player.js"></script>
 ```
 
-Only one player is supported per page in this version. The player logs a clear console message and does not initialize if no `[data-vr-web-player]` container is found, if multiple containers are found, if the container has no video, or if `data-projection` is not `vr180` or `plane`.
+```html
+<button
+	type="button"
+	data-vr-web-launcher
+	data-media-type="image"
+	data-projection="vr180"
+	data-src="vr180-sbs-image.jpg"
+	data-title="Temple Hall"
+	data-crossorigin="anonymous">
+	<img src="temple-thumb.jpg" alt="Temple Hall">
+</button>
 
-## Video format
-This version supports 2:1 side-by-side video using H.264 or HEVC in an mp4 file. It does not support over-under, MV-HEVC, APMP, or `.aivu`.
+<script type="module" src="https://pages.f-40.com/VR-Web-Player/vr180player/vr180-player.js"></script>
+```
+
+A page can contain any number of launchers. Each launcher represents one SBS media item. A launcher click goes straight into immersive WebXR when `immersive-vr` is supported. When immersive WebXR is unavailable, the same click opens a modal with the left-eye fallback view.
+
+Launcher attributes:
+
+- `data-vr-web-launcher`: required marker.
+- `data-src`: required media URL. For image carousels, provide at least two comma-separated image URLs.
+- `data-media-type="image|video"`: optional when the media type can be inferred from the URL extension.
+- `data-projection="vr180|plane"`: defaults to `vr180`.
+- `data-title`: optional display title.
+- `data-carousel`: optional image carousel mode.
+- `data-head-lock="auto|position|none"`: optional positional comfort mode. It defaults to `auto`, which position-locks `vr180` media to the headset to avoid false 6DoF parallax, while leaving `plane` media fixed like a screen.
+- `data-poster`, `data-type`, and `data-preload`: video helpers.
+- `data-crossorigin`: optional media CORS mode, usually `anonymous` for CDN media.
+
+Use `data-projection="plane"` for flat 3D media on a rectangular plane:
+
+```html
+<button
+	type="button"
+	data-vr-web-launcher
+	data-media-type="video"
+	data-projection="plane"
+	data-src="flat-sbs-video.mp4"
+	data-poster="poster.jpg"
+	data-title="Flat 3D Demo"
+	data-type="video/mp4"
+	data-crossorigin="anonymous">
+	<img src="poster.jpg" alt="Flat 3D Demo">
+</button>
+```
+
+Use `data-carousel` for multiple SBS still images in one immersive session:
+
+```html
+<button
+	type="button"
+	data-vr-web-launcher
+	data-carousel
+	data-media-type="image"
+	data-projection="vr180"
+	data-src="first-sbs-image.png, second-sbs-image.png"
+	data-title="VR180 Stills"
+	data-crossorigin="anonymous">
+	<img src="first-thumb.jpg" alt="VR180 Stills">
+</button>
+```
+
+`[data-vr-web-player]` is now an internal container created by the launcher at runtime. Authored pages should use `[data-vr-web-launcher]`.
+
+## Media format
+This version supports side-by-side media only:
+
+- Video: 2:1 side-by-side video using H.264 or HEVC in an mp4 file.
+- Image: side-by-side still images in browser-supported image formats such as PNG, JPEG, or WebP.
+
+It does not support over-under, MV-HEVC, APMP, or `.aivu`.
 
 ## How it works
-When the page loads, the video is embedded normally with a play button over the poster frame. When the user clicks play, the player checks for `navigator.xr` and `immersive-vr` support.
+When the page loads, the script binds every `[data-vr-web-launcher]` on the page. When the user clicks a launcher, the player checks for `navigator.xr` and `immersive-vr` support, then splits between immersive entry and fallback modal display.
 
-- In WebXR, `vr180` maps the left and right halves of the SBS video onto the matching eyes of a 180 degree sphere.
-- In WebXR, `plane` maps the left and right halves onto the matching eyes of a floating 16:9 video plane.
-- Outside WebXR, both modes render only the left half of the SBS video so viewers do not see the raw double image.
+- In WebXR, `vr180` maps the left and right halves of the SBS media onto the matching eyes of a 180 degree sphere. In the default `auto` head-lock mode, the sphere follows headset position but not headset rotation.
+- In WebXR, `plane` maps the left and right halves onto the matching eyes of a floating 16:9 plane.
+- Outside WebXR, both modes render only the left half of the SBS media so viewers do not see the raw double image.
+- Video controls include a loop toggle for indefinite replay.
+- Static images show only applicable controls; playback, seek, and mute controls are video-only.
+- Image carousels replace skip buttons with previous/next image controls, so you can change stills without leaving the immersive session.
+- Controller pointers and lightweight controller overlays appear after controller interaction, then fade away after a short idle period so they do not distract from viewing.
 - Control icons are embedded from [Lucide](https://lucide.dev/) SVG definitions, so no PNG icon assets are required.
 
 ## Demo
-Run `npm run build`, then open this repository's `index.html` through a local web server and switch `data-projection` between `vr180` and `plane` to test both modes.

 This builds the TypeScript player once, then serves `index.html` with Vite at a local URL.
 
+For headset testing, the page must be a secure context before the browser will expose immersive WebXR. A LAN URL such as `http://192.168.x.x:5173/` is useful for checking layout and media loading, but it will usually not show the headset's immersive VR prompt. Use an HTTPS URL with a trusted certificate, a trusted tunnel, or a deployed CDN/Pages URL for immersive testing.
+
+## F40 Pages deploy
+This repo includes a Gitea Actions workflow at `.gitea/workflows/publish-pages.yml`. It builds the test app into `dist/` and uploads it to the shared F40 Pages R2 bucket using the layout:
+
+```txt
+sites/{site-name}/releases/{git-sha}-{run-attempt}/
+sites/{site-name}/current.json
+```
+
+By default, this repo uses:
+
+```sh
+npm ci && npm run build:test-app
+```
+
+The `build:test-app` script compiles the player, copies the generated `vr180player/` CDN assets, copies the simplified `test-pages/` app, and optionally copies `media/` if that local directory exists.
+
+Required Gitea secrets:
+
+- `F40_PAGES_R2_ACCOUNT_ID`
+- `F40_PAGES_R2_BUCKET`
+- `F40_PAGES_R2_ACCESS_KEY_ID`
+- `F40_PAGES_R2_SECRET_ACCESS_KEY`
+
+Optional Gitea variables:
+
+- `F40_PAGES_SITE_NAME`: defaults to the repository name.
+- `F40_PAGES_BUILD_COMMAND`: defaults to `npm ci && npm run build:test-app`.
+- `F40_PAGES_OUTPUT_DIR`: defaults to `dist`.
+
+When the middleman router serves the current release at `https://pages.f-40.com/{site-name}/`, the generated player can also be used as a CDN from:
+
+```html
+<script type="module" src="https://pages.f-40.com/VR-Web-Player/vr180player/vr180-player.js"></script>
+```
+
+For stronger CDN caching, the router can expose immutable release URLs and use the `current.json` file only to resolve the latest release.
+
 ## Development
 The player source is TypeScript in `src/vr180player/`. Generated JavaScript files in `vr180player/` are ignored by git so CI/CD can build and publish them from source.

 npm install
 npm run dev

 ```
 
 Edit the TypeScript source files rather than generated JavaScript. A typical CI/CD publish step should run `npm ci`, `npm run build`, then publish `vr180player/` with its generated `.js` files and CSS.
+
+## Upload to Cloudflare R2
+Copy `.env.r2.example` to `.env.r2`, then fill in your R2 account, bucket, and S3-compatible access key credentials.
+
+```sh
+npm run upload:r2:dry-run
+npm run deploy:r2

+By default this uploads the built `vr180player/` folder under the `vr180player/` object prefix. Change `R2_SOURCE_DIR` or `R2_PREFIX` in `.env.r2` if you want a different source folder or CDN path.
