Footer: subtle link to the GitHub repo

[adewale]

Footer now carries two text-links separated by an interpunct (the same separator the eyebrows use):

adewale/pythonbyexample · Python 3.13 docs

The owner/repo form is GitHub-native — readers who recognise the pattern know exactly where it goes — and the muted .meta colour + accent underline keeps it the same visual weight as the docs link beside it.

Why this location

• Footer is the conventional "about this site / external references" slot across docs sites (Stripe, MDN, Replit, GOV.UK).
• Readers who finish reading land there naturally; readers who don't are unbothered.
• Existing footer already holds the Python docs link with this exact treatment, so the new link is in the design vocabulary by construction.

Why this text

• Mirrors GitHub's native naming convention — anyone who has read a clone command or visited a repo URL recognises owner/repo as "this is the repository."
• Same syntactic shape as "Python 3.13 docs" (short, no verb, names the destination).
• Quietly tells you who owns it without needing the word "by" or "maintained by".

What I considered and rejected

• A header nav slot — would re-introduce the header-is-external chrome ambiguity that PR Marginalia: figures, contracts, and journey-section rendering #1 deliberately separated (header is now in-site, footer is external).
• A brand-mark suffix (Python By Example ↗) — fights with the hero-collapse scroll animation and adds a busy element next to the morphing wordmark.
• "Source on GitHub" / "GitHub" / "Edit on GitHub" — all valid; "adewale/pythonbyexample" felt most authentic to where the link goes.

Verification
