com.dryan.timeline.entry

The dryan.com timeline's per-entry data, carried in the `content` open union of a site.standard.document record. The document holds what every entry shares (title, path, publishedAt, description, textContent, tags, coverImage); this holds the entry type, the day it belongs to, and the type-specific detail. atproto records cannot carry floats, so measurements that are not whole numbers (speeds, heart rates, coordinates) are decimal strings.
