The `@a11y` test checked two heading rules against the main article. Both reached zero site-wide, so extend the same test to the full WCAG 2.1 A/AA rule set. Only `heading-order` and `page-has-heading-one` fail, guarding the zero they already reached. Everything else reports without failing: docs carries a backlog that would otherwise block every PR on a required check. As a class of issue reaches zero, its rule moves into `ENFORCED_RULES` so it can't come back. `A11Y_ENFORCE_ALL=1` previews failing on everything. Scanning stays limited to the article, and `LEAN_EXCLUDED_RULES` drops `color-contrast` plus eight document-level rules, roughly halving scan time on a large page. Contrast is most of that time and finds nothing inside an article — it comes from shared tokens and chrome, which a content change can neither introduce nor fix. The document-level rules target `<html>`, `<head>`, and `<body>` and so can't fire within an article at all. Cross-origin frames are skipped via legacy mode. Without it Playwright hands axe every frame, so embedded YouTube players get scanned and YouTube's markup is reported as ours — 11 of 15 violations on a page with one embed. Axe's `iframes: false` run option does not do this, because the Playwright integration enumerates frames itself. Two failure modes that previously read as "clean" now fail loudly: a page that didn't load is recorded as a failed load rather than an a11y failure, and a scan seeing implausibly few elements is rejected instead of reporting a false pass, which catches scanning before hydration finishes.
