   THE FORTNIGHT — /how-we-work/

   Markup: templates/website/_fortnight.html
   Data:   website/engagement.py

   Its own stylesheet, for the reason regtimeline.css and packstack.css
   are: a graphic defined inside how_we_work.css can only ever appear on
   /how-we-work/. Whichever page shows it must link this file —
   `{% block extra_head %}` is not inherited, and a graphic whose
   stylesheet never loads prints as unstyled body text flush to both
   edges, which is what shipped on two region pages on 2026-08-19.
