WIP: lists/channel (trail), element/block (mark)

[hzoo]

(arena like lexicon)
trail is an arena channel (a list of things), a mark is an element in the list, a block in arena. trails are just links to atproto things or urls so it could be a trail itself.
profile page shows lists of trails: https://henry.ink/profile/henryzoo.com
example trail: https://henry.ink/profile/henryzoo.com/trail/3lxzmgaa75sti
bookmarklet to add a trail: https://henry.ink/tools/bookmarklet, https://henry.ink/tools/quick-mark

• but we need code to be able to render diff atproto lexicons, one at a time
• i think if you dont have a UI that people are already on, it's hard to input a lot of data unless someone is very motivated? can use a bookmarklet or extension but not sure that is for a new user. ideally it's a inline button next to the thing itself (like a tweet + bookmark, or bsky post + bookmark, or arena block which lets you add to any channel if you find it interesting). if there is no UI with content then you need to copy paste the url and create an entry but i find that tedious.
