Replaces the previous synchronous form-POST flow (which left users
staring at a white screen for the duration of the upstream fetch)
with an SSE-driven status page that shows real-time progress through
each stage of the bypass attempt.
Bypass pipeline:
- Direct fetch with Googlebot UA (unchanged for non-Medium URLs)
- Detect Cloudflare-style anti-bot challenge pages in the response
- Fallback 1: Freedium (freedium-mirror.cfd, then freedium.cfd) for
medium.com hosts — short-circuited before direct fetch since
Cloudflare consistently blocks the Googlebot UA from non-Google IPs
- Fallback 2: archive.org Wayback Machine snapshot
- Fallback 3: archive.today / archive.ph / archive.is / archive.li
mirrors (all four tried in sequence)
- Surface a clear error if every source fails
UI:
- Animated step list with spinner / checkmark per stage
- Progress bar and elapsed-time counter
- Honest error box with retry button instead of a blank page
