Every site's announcement bar now follows one template:
Line 1 — identity + primary CTA (what is THIS site)
Line 2 — the book (or, on book sites, the other volume)
Line 3 — "Alongside the book:" sibling row (3 most-relevant verbs)
Line 4 — newsletter
The book is the anchor of the curriculum; every other site is a verb
applied to it — TinyTorch (build), Hardware Kits (deploy), MLSys·im
(simulate), Labs (explore), Slides + Instructors (teach). Making that
shape visible in every bar turns nine independent sites into chapters
of one curriculum.
Removed stale copy: "Happy New Year!" on kits + labs, "coming in 2026"
on labs (we are in 2026; replaced with "Coming Summer 2026"), TinyTorch
v0.1.10 single-line release notice (belonged in a release changelog,
not the always-visible nav bar).
Normalized outbound links: /book -> /vol1/ and /vol2/, consistent
trailing-slash hygiene on every URL. Newsletter link points to
https://mlsysbook.ai/newsletter/ (the actual Quarto page) instead of
#subscribe (which only resolves on the landing page).
The landing site (mlsysbook.ai) uses a 5-line variant that covers all
four learner verbs + the teacher-tools row; every other site uses the
4-line form.
StaffML is a Next.js app, not a Quarto site, so its banner is out of
scope for this PR and will ship as a separate React component change.
All 7 public-facing Quarto sites now have consistent announcement
bars with icon: megaphone, type: primary, position: below-navbar.
Previously only tinytorch, labs, kits, book, and mlsysim had them.
