No Netlify PR preview for this edition — reviewers have no rendered page to check

What is missing

This is the only edition in the lecture-python-programming series without a Netlify PR preview. The English source, .fa and .fr all deploy one per pull request; this repository's ci.yml has no Netlify step, and gh api repos/.../actions/secrets returns no NETLIFY_SITE_ID here, where .fa and .fr both have one.

Why it matters here specifically

Translation review depends on reading rendered pages. A reviewer working through a sync PR in .fa or .fr can open the preview and see the lecture as a reader will; here they can only read the diff.

It has already cost us twice in the last day:

• #80 — the language switcher plus five URL fixes — merged on weaker evidence than its .fa and .fr counterparts. Both of those were verified against a real deploy preview; this one could only be checked with a local build and a passing CI run.
• #81 — the bump to theme 0.21.0 — carries a documented layout change at 1024–1499px viewports, exactly the kind of change that wants a rendered page. There is nothing to look at.

What is needed

Two halves, and the first is the blocker:

1. A Netlify site for this repository, and its NETLIFY_SITE_ID as a repo secret. NETLIFY_SITE_ID is per-site and set at repo level — .fa and .fr each carry their own — so it cannot be inherited from the org. This step needs someone with Netlify and repo-admin access.
2. The workflow step in ci.yml. Small, and copyable from a sibling.

One decision to make first

The series currently uses two different mechanisms, so this should follow whichever is intended as the standard rather than adding a third data point:

.fr is the most recently set up of the three and uses the QuantEcon-maintained wrapper, which suggests that is the newer house pattern — but it is worth confirming rather than inferring from one data point. Note also that the .fr preview posts a PR comment rather than a commit status, so it does not appear in gh pr checks; whichever is chosen, that difference is worth knowing.

Happy to write the ci.yml half once the site and secret exist and the mechanism is settled.

Confronta i passaggi del workflow in ci.yml con i repository .fa e .fr affini, inclusa la loro azione Netlify e la configurazione del secret NETLIFY_SITE_ID. Prima conferma quale meccanismo di anteprima sia lo standard previsto; quindi, una volta che il sito e il secret del repository esistono, aggiungi il passaggio a ci.yml. Il lavoro è completato quando una pull request produce un’anteprima Netlify renderizzata che i reviewer possono aprire.
