* Fixed: Do not set `src` for images on Firefox, since that causes animations to reset when a new image is added to the DOM with the same `src`. For some reason. Thanks, Firefox.
* Fixed: The FFZ Control Center, Emote Cards, and Link Cards are now all aware of each other in a limited sense. The most recently interacted-with window will appear on top of the others.
* Fixed: Channel page links not having enhanced tool-tip preview support. (Still no link cards when you click them, but it's a start.)
* Developer: Made it so the Link Tester in Debugging > Data Sources will properly open link cards, as long as you have link cards enabled.
* API Added: Update to the latest FFZ rich tokens format, which has a new `i18n_select` token. This allows, for example, the link preview service to return multiple languages of titles and descriptions for a YouTube video so that your client can pick the best one to display.
* Experiment Changed: The "API-Based Link Lookups" experiment now has a third option that uses Cloudflare Workers. It's set very low while I try to gauge how much traffic it would see, and if this is a viable option.
* Added: Link Cards. As an option, you can open a preview card when clicking on links in chat. These preview cards function similarly to the existing tool-tip or rich embed options but can provide for enhanced interaction (e.g. an embedded video player), with potential for more in the future.
* Changed: When using a custom theme with a dark background, use lighter border colors.
* Changed: Draw the FFZ Control Center and other dialogs with rounded corners.
* Fixed: Issue when clicking certain global Twitch emotes preventing the emote card from appearing correctly.
* Fixed: Issue with URL/safety data not being loaded correctly from the link service when the overall result was an error.
* Fixed: Issue with link tool-tips still appearing, but with no content, when link tool-tips are disabled.
* Fixed: Issue where (re)subscription notices in chat for multiple-month-at-once subscriptions would not be displayed correctly.
* Fixed: Tool-tips not displaying correctly in chat pop-outs in some circumstances.
* Fixed: Incorrect border styles when the chat is in portrait mode.
* Experiment Added: Set up an MQTT-based PubSub system. Let's see how well this scales.
