[BUG] UI: Live session black screen due to naming collision on "pc" variable

[khanhquocnguyen]

Issue: The live session player fails to load (black screen) with Uncaught SyntaxError: Identifier 'pc' has already been declared.

Root Cause: The player script declares const pc in the global scope. This conflicts with several Crypto Wallet extensions (like Hot Wallet, Rabby, etc.) that also inject a pc variable (often for WebRTC leak protection) into the global declarative record.

Environment: Chrome with Hot Wallet extension enabled.

Suggested Fix: Please consider wrapping the player script in an IIFE or renaming the global pc variable to something more unique (e.g., _steel_pc) to avoid collisions with third-party extensions.
