clients.js (the registry shared across the zzstoatzz sites — same localStorage key, so the preference follows the reader between projects), a gear popover for choosing where atproto identities open (bluesky, blacksky, witchsky, red dwarf, PDSls), and a post-render sweep that tags bsky.app profile links in rendered markdown so they honor the preference and stay fresh when it changes. authors keep writing plain bsky.app URLs.
