The website
Three files and a folder of marks. No build step, no dependencies, no
framework — open index.html and it works, including from a file:// URL.
index.html the page
style.css the palette, transcribed from include/theme.h
app.js two behaviours: the boot log types, sections fade in
Assets/ shift.svg (the logo), uberblock.svg (SchFS), guru.svg (PSOGM)
The rules it follows
The palette is not a design decision. It is include/theme.h, copied. A
site describing an operating system should look like the operating system, and
copying the header means the two cannot drift apart by accident.
PSOGM purple appears exactly once. #4B1D9A is on the crash-screen section
and nowhere else, because ../branding/README.md says
it means the machine stopped and that a colour used everywhere means nothing.
If it shows up in a second place, that is a bug in the page.
The typefaces are the ones the OS ships. Roboto for text and JetBrains Mono
for the system voice — both already in ports/, both already in NOTICE. They
are requested from the system rather than downloaded: a font file would be
larger than the entire rest of the site.
The script is optional. If app.js fails to load the page is still
complete and still readable. Everything it does is decoration, and it honours
prefers-reduced-motion by doing none of it.
The boot log is real. The lines in app.js are from an actual boot, not
invented. The timer calibration line is there deliberately; see section 13 of
../history/kernel.md for what it cost.
Editing it
The numbers in the Numbers section are measured, not estimated, and they go stale. To refresh them:
find kernel include -name '*.c' -o -name '*.h' | xargs wc -l | tail -1
grep -c '^SYSCALL' kernel/sys/table.inc
The feature cards carry a tag — runs, in progress, or designed — and the
tag is a promise. Anything marked runs is in the tree and works today. When
that stops being true, change the tag rather than the wording.
