print and web output, and @tt{C)} organize an ever-growing collection of hundreds of individual
notes and articles without noticable loss of speed.

The solid-line connections indicate explicit @racket[require] relationships. Dotted arrows generally
indicate implicit exports in the Pollen environment: docs and metas to templates,
@seclink["pollen-rkt"]{@filepath{pollen.rkt}} to source documents and templates. The orange lines
The modules are arranged vertically: those on the upper rows provide bindings which are used by
those on the lower rows. The bottom row are the @tt{.poly.pm} files that make up @tech{articles} and

@seclink["crystalize-rkt"]{@filepath{crystalize.rkt}}.

Individual articles, while they are being rendered to HTML pages, save copies of their metadata and

Any pages that gather content from multiple articles, such as Series pages and the RSS feed, pull
