Suggestion: SigCLI for automated cookie management

[brelian]

Problem

For authenticated downloads (Bilibili premium, Douyin, etc.), users pass cookies via -c "cookie_string" or -c cookies.txt. This means manually opening DevTools, copying the cookie header, and re-doing it whenever the session expires.

Suggestion

SigCLI automates browser login and cookie extraction:

# One-time setup
npm install -g @sigcli/cli && sig init
sig login bilibili  # Opens browser for QR scan

# Use with lux — pass cookie string directly
lux -c "$(sig get bilibili --no-redaction --format value)" "https://www.bilibili.com/video/BV..."

Benefits:

• No manual DevTools cookie copying
• Auto-refresh when cookies expire (sig watch)
• Encrypted storage, multiple accounts
• Works on remote/headless machines (sig sync)
• Uses real Chrome/Edge — no bot detection

This is just a user-workflow suggestion, not a code change request. Happy to contribute a docs section if helpful.
