   Newsreader, SELF-HOSTED. The files are served from this repo and Google's
   CDN is never contacted by a visitor — fonts.gstatic.com logs visitor IPs
   in the US, which is a GDPR liability and pointedly off-brand for a site
   about EU data residency.

   Two static instances (400, 500) rather than the variable font. The
   variable file carries optical-size and weight axes and costs 129kB;
   narrowing the axis range does not shrink it, because Google serves the
   same file. These two are 45kB combined and cover every weight in use.

   Latin subset only — it covers the whole page (é in "Société", £, the
   em/en dashes). The ↗ glyph is outside it and falls back to the system
   serif, which is imperceptible at that size.
