Thought I'd share some ideas I've been floating, to implement a unified branding across all instances. Instances could opt-in for a consistent identity across the platform, using an official trademark with their instance address embedded below it. Instances that use "lemmy" in their second-level domain name would simple append their .tld (such as .world), or use .sld.tld when "lemmy" is accessible from a subdomain (such as .dbzer0.com). Seemingly unrelated domain names, such as beehaw.org, would just omit the leading dot.
The navbar background itself could be further customized by the local instance. I imagine something like a watermark of a globe for lemmy.world, or a watermarked maple leaf for lemmy.ca, etc.
Obviously this is a very rough take on things (including the art style), and I'm just brainstorming ideas at this point.
What are your thoughts?
