Val Town service that fetches bookmarked articles tagged "toread" from your Kipclip (AT Protocol) account, converts them to EPUBs, and serves them to the CrossPoint e-reader.

How it works#

A cron job runs every hour, reading community.lexicon.bookmarks.bookmark records from your AT Proto repo
Filters for bookmarks with the configured tag (default: "toread")
Fetches article HTML and cleans it with Mozilla Readability
Generates minimal EPUB files, stored in Val Town Blob storage
The e-reader fetches the article list and downloads EPUBs via HTTP
