- setup.sh: idempotent one-shot droplet provisioner — agentbbs on :22 (admin OpenSSH moved to :2202), rootless podman, Caddy front end for https://bbs.profullstack.com with tilde-style /~user homepages - internal/sites + domain@ SSH route: self-service custom domains (ssh domain@host add example.com) backed by a symlink farm and an on-demand-TLS ask endpoint so Caddy only issues certs for mapped hosts - internal/mail + join@ email verification: optional email at signup, confirmation link served by a loopback /verify endpoint behind Caddy - internal/source + cmd/ascii-live: live video → terminal ASCII groundwork (docs/ascii-live.md) - store: additive sqlite migrations (email/verify columns, domains table) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

// Command ascii-live previews a live video source as truecolor ASCII in the
|
|
// local terminal — the Phase 0 deliverable of docs/ascii-live.md. It shares
|
|
// the source adapter (internal/source) and renderer (internal/ascii) with the
|
|
// AgentBBS SSH route, so what you see here is what tv-<slug>@ will serve.
|
|
//
|
|
// Usage:
|
|
//
|
|
// ascii-live watch <url> [--fps N] [--width COLS]
|
|
//
|
|
// ascii-live watch "https://youtube.com/live/<id>"
|
|
// ascii-live watch "https://example.com/stream.m3u8"
