The design depends on three specific families, and loading them from
fonts.googleapis.com means the UI silently loses its character exactly
where it is used most: Bromite is a de-googled browser whose users
routinely block Google's font domains, and the backend is reachable over a
LAN with no internet route. In both cases the page fell back to Georgia
and a system sans.
Five latin-subset woff2 files, ~120 KB total, in a binary already 27 MB —
the cost is noise, and //go:embed static picks them up with no build
change (backend/Dockerfile already copies static/). Latin only because the
UI is English; woff2 only because every browser that can run this app
supports it, so there is no second format to carry. DM Sans ships as one
variable file, which covers the whole 400-700 range the design uses for
the price of a single request.
staticHandler registers the .woff2 MIME type: Go's built-in table has no
entry for it and the scratch image has no /etc/mime.types, so the fonts
would otherwise be served as application/octet-stream. The two faces
above the fold are preloaded, since they are now discovered a stylesheet
late rather than from a preconnect.
