~x-ai/grok-latest → B (2:3)

B replaces scattered hardcoded host/case logic with a shared HOSTNAME-driven get-base-url (plus window.location.origin on the client), fixing OAuth/redirect correctness across login, Linear, Spotify, Twitter, and YouTube and enabling real staging deploys—broader lasting design impact than A’s narrow Reddit filter. A is a clean, tested skip of stickied/pinned children, but it only trims one import path and does less for cross-environment correctness.
