The previous styling was brittle and ended up breaking in very small
phone-size views with the text overflowing the boundaries of the page.
The right fix is to move those heading outside the portico-header
class, since the CSS for that isn't generally appropriate here.
This flag allows rendering as a single isolated page, without the
navigation in header and footer that otherwise provides links to the
rest of the site.
The portico layout, including the styling of the "hero" area at top,
all remains the same.
We don't yet ever set this flag; that'll come next.
xmlns:svg is an XML namespace declaration that would be valid in XHTML
but not in HTML. Even in XHTML, it wouldn’t be necessary because we
don’t write SVG tags prefixed like <svg:circle>, only unprefixed like
<circle>.

We have a good "Help Center" section in the footer, where a user
may already expect to look for help/support related requests, so
we can replace the navbar spot there with the "Why Zulip" page link.
This creates a dropdown in place of the normal register/login links
you get when logged out, with an option to go to the app or log out if
that appears you click on the avatar.
A bit more work is needed to make this look really good, but it's a
great start.
Now that this page redirects to upstream, make our own links
to it point directly upstream. This saves a redirect, and
makes it more transparent where the link points if the user
examines it before following.
