Changelog pages, navbar to footer: the release notes open the page, as one thread, filtered by a row of pills or grouped by month beside a filter rail, then a signup or a closing line. Three finished pages.
A section is one full-width band: a hero, a pricing table, a footer. A page stacks several of them into a finished screen, from the navbar to the footer. The sections are the parts, the page is one tested way to put them together.
