The subscribe modal (shared across the book, site, labs, kits, and mlsysim subsites) was a plain div overlay: - No role="dialog", aria-modal, or accessible name, so screen readers never announced it as a dialog and could wander into the page behind the overlay. - No focus trap: Tab walked out of the modal into the visually hidden background page. - Focus was never returned to the triggering element on close, dropping keyboard users at the top of the document. - Open/close animations played regardless of prefers-reduced-motion. Changes to the canonical shared/scripts/subscribe-modal.js: - role="dialog" aria-modal="true" aria-labelledby on the container, with an id on the existing title. - Tab/Shift+Tab now cycle within the modal's visible, enabled controls (computed per keypress, so the trap also works on the post-submit success view). - The opener element is saved on openModal() and refocused on close. - Animations are disabled under prefers-reduced-motion: reduce. Mirrors regenerated with shared/scripts/sync-mirrors.sh (CI drift check). Escape-to-close and overlay-click behavior unchanged.
MLSysBook — Unified site (landing)
This directory is the Quarto source for the public landing and community experience at mlsysbook.ai: home, about, community, newsletter sync, and related shared pages (together with assets under shared/).
Note
📌 Early release (2026)
The unified site shipped with the 2026 MLSysBook refresh. Information architecture, copy, newsletter wiring, and styling are actively iterated as the book and sibling projects evolve.
