Get Started page has four h1 headings (WCAG 1.3.1)

🕋 Website

The Get Started page renders four <h1> elements, so the document has four competing top-level headings instead of one.

https://pytorch.org/get-started/locally/

h1  Get Started
h1  Installing on macOS
h1  Installing on Linux
h1  Installing on Windows

The three install headings come from this repo, and each opens with a markdown #:

• _get_started/installation/mac.md
• _get_started/installation/linux.md
• _get_started/installation/windows.md

Those files are included into a page that already carries its own h1, so the # becomes a second, third and fourth top-level heading rather than a section heading under it.

Why it matters

Headings are how screen reader users navigate a long page. Most screen readers offer "jump to next heading" and a heading list, and both rely on the levels describing a real outline. Four h1s say the page has four separate documents in it, so the outline stops being useful for exactly the page a new user is most likely to be reading carefully while installing something.

This is WCAG 2.2 1.3.1 Info and Relationships, Level A.

To Reproduce

1. Go to https://pytorch.org/get-started/locally/
2. Run in the console:

[...document.querySelectorAll('h1')].map(h => h.textContent.trim())

3. Four headings are returned rather than one.

Expected behavior

One h1 per page. The three install headings become ##, which puts them under "Get Started" where they belong and leaves the rendered page looking the same.

Two things I could not determine from outside

Both are about the page chrome rather than the content, and I suspect they are not owned by this repo, so I am asking rather than reporting:

1. There are two role="contentinfo" landmarks on every page I checked, one on div.nectar-global-section.before-footer and one on #footer-outer. There should only be one, otherwise landmark navigation offers two "footers".
2. The homepage h1 is "JOIN US", which is a conference banner rather than a description of the page.

Both look like they come from the WordPress theme wrapping the Jekyll content, not from this repository. If that is right, I would be glad to know where they should be raised instead.

Happy to open a pull request for the # to ## change if that is useful.

Start by inspecting the markdown headings in _get_started/installation/mac.md, _get_started/installation/linux.md, and _get_started/installation/windows.md, then reproduce the issue with the provided browser-console query on the Get Started page. Done means the rendered page has one h1, the three installation headings appear as h2 elements, and the page's visual appearance is unchanged.
