Can I vibecode Vimeo?

Build me a personal ad-free video host to replace Vimeo. Requirements:

- Node + Express on a small VPS, Cloudflare R2 for the media, Cloudflare in front of
  it. Server-rendered pages, hls.js for playback, no frontend framework.
- I run `pub <file.mov> --title "..."`; ffmpeg builds an HLS ladder at 1080p, 720p,
  and 540p with a master.m3u8 and a poster JPEG, then rclone syncs it to R2.
- Each video gets /v/<slug>: player, title, description, and a copyable embed
  snippet. /e/<slug> is the bare iframe target with no page chrome.
- Privacy is one field per video · public, unlisted (random slug, indexed nowhere),
  or password, checked server side before the manifest URL is handed out.
- Metadata lives in SQLite via better-sqlite3. Media never stays on the VPS disk
  after upload. R2 keys and the Cloudflare zone come from .env.
- A /library page behind basic auth lists every video with duration, size, and this
  month's egress pulled from the Cloudflare GraphQL API, so the bill is never a
  surprise.
- No accounts, no ads, no telemetry, and no tracking pixels in the embed.
- Out of scope: live streaming, monetization, and comments. Do not build a social
  feed or a recommendation surface. Captions can come later from whisper.cpp.
- README: R2 bucket and custom domain setup, why the CDN is not optional, and an
  honest warning that a video going viral is now your invoice, not Vimeo's.
