docs: align upload guides with code and add consistency test

- Updates `content/docs/guides/upload-content.md` and `getting-started.md` to accurately reflect supported file types, S3-compatible storage options, and metadata requirements.
- Clarifies CORS configuration steps for R2 vs. generic S3.
- Adds `tests/docs/verify-upload-claims.test.mjs` to programmatically ensure documentation claims match frontend code attributes.

 ### Step 2: Prepare Your Video
 
-1. Host your video at an HTTPS URL that browsers can stream directly. If you are uploading a file directly via bitvid, we accept **MP4, WebM, MOV, MKV, TS, M3U8, MPG, and MPEG** (Max 2GB recommended). For external hosting, ensure the format is streamable (MP4/WebM/HLS/DASH). You can use your own CDN, Cloudflare Stream, an R2 bucket, or any static site host—as long as the link begins with `https://`.
-2. (Optional but recommended) Generate a WebTorrent magnet so viewers can fall back to peer-to-peer delivery. Desktop apps like [WebTorrent Desktop](https://webtorrent.io/desktop/) or command-line tools can create the magnet for you.
-3. Double-check that either the hosted URL or the magnet (or both) is ready before you open the Upload modal.
+1. **Format:** We accept **.mp4, .webm, .mov, .mkv, .ts, .m3u8, .mpg, .mpeg** (Max 2GB recommended).
+2. **Hosting:** You can upload directly via bitvid (requires your own Cloudflare R2 or S3 bucket) or host your video elsewhere (CDN, Cloudflare Stream, etc.) and provide the HTTPS URL. For external hosting, ensure the format is streamable (MP4/WebM/HLS/DASH).
+3. **(Optional) WebTorrent:** If hosting externally, you can generate a WebTorrent magnet so viewers can fall back to peer-to-peer delivery.
 
 ### Step 3: Share on bitvid
 
 1. Click "Share a Video" on bitvid to open the upload modal.
 2. Choose your upload mode:
-   - **Upload Video**: Select a file from your device to upload directly to your Cloudflare R2 bucket. If you haven't configured storage yet, click **"Configure Storage"** to enter your R2 credentials (Account ID, Access Key ID, Secret Access Key, Bucket Name, Public Access URL) in your Profile settings.
+   - **Upload Video**: Select a file from your device to upload directly to your Cloudflare R2 or S3-compatible bucket. If you haven't configured storage yet, click **"Configure Storage"** to enter your credentials (Account ID/Endpoint, Access Keys, Bucket Name, Public URL) in your Profile settings.
    - **External URL**: If you already host your video elsewhere, paste the HTTPS URL and (optionally) a WebTorrent magnet link.
-3. Review the rest of the form: add a description and thumbnail, decide whether to allow comments, and set the NSFW or "For Kids" toggles to match your content. Explore the metadata section to fill in captions, duration, publish time, hashtags, participants, and other fields so first-time viewers have all the context they need.
