Reddit's "new" web UI (`reddit.com`) is a Lit / web-components SPA built around custom elements (`shreddit-post`, `shreddit-comment`, `faceplate-*`). This makes DOM extraction unusually reliable — the custom element tags are stable and exposed on the element itself (no hashed class names). Use the browser when you're logged in (private subreddits, NSFW gates, rate-limit avoidance). For fully public content, the JSON API path below is faster.
