Closes DOCS-1233

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Test coverage. The docs accessibility check now covers the full WCAG 2.1
A/AA rule set instead of two rules.

**Note:** This PR tests _only_ the main article of changed pages
(meaning, the content itself). A follow-up Linear issue is to address
scanning the pieces outside of that: header, navigation, and interactive
elements.

## What is the current behavior?

The `@a11y` test in `e2e/docs` runs two axe rules against each in-scope
page, `heading-order` and `page-has-heading-one`. Both already pass
everywhere, so the check only guards a result we have. Nothing else in
WCAG A/AA is checked.

## What is the new behavior?

The same test runs the full WCAG 2.1 A/AA rule set.

- **Existing debt does not block PRs.** Only the two heading rules fail.
Everything else reports.
- **The check stays fast.** It scans the article only and skips nine
rules that cannot fire there. Scan time drops from 2405ms to 981ms.
- **Findings belong to us.** Legacy mode excludes cross-origin frames.
YouTube embeds were counting against us, 11 of 15 violations on one
page.
- **A pass carries meaning.** A 404 reports as a load failure, not an
a11y bug. A page scanned before it hydrates warns instead of quietly
reporting clean.

## How the findings appear

The test is named `has no blocking accessibility violations`, so a
failure listed by CI is always something to fix. It is not named for the
full rule set, because a green check would then claim more than the
check verifies.

| | Rules | Where you see it |
| --- | --- | --- |
| Blocking | `heading-order`, `page-has-heading-one` | Test failure, so
the runner reports it on the PR |
| Reported | Everything else in WCAG A/AA | `::warning` annotation on
the run |

An annotation looks like this, on a run that still passes:

```
::warning title=Accessibility::/docs/guides/database/functions has 1 non-blocking accessibility finding(s): frame-title (4)
```

The full axe result for each page is attached to the report as
`axe-results.json`.

## Matching the Studio ratchet

This follows the ESLint ratchet in `apps/studio`. That pattern warns on
pre-existing debt rather than blocking on it, surfaces findings as
annotations rather than PR comments, and promotes a rule to an error
once its violations reach zero.

The mechanism here is `ENFORCED_RULES` in `utils/axe-helpers.ts`. The
two heading rules are on it because the heading-hierarchy work drove
them to zero site-wide.

The intent is to migrate rules into that list one at a time. Pick a
rule, fix its violations, then move it into `ENFORCED_RULES` so it
cannot come back. An exhaustive scan of the site groups the current
backlog by root cause to sequence that work, and two fixes cover 99.1%
of it.

Studio keeps per-file baseline counts, which this does not. A whole-rule
list is coarser, and it works here because docs violations reach zero
across the site rather than per file.

## Manual testing

Install the browser once, then run each step from the repo root. Every
command scans production, so you do not need a local docs server.

```bash
pnpm -C e2e/docs exec playwright install chromium
```

1. Confirm a reported finding does not fail the check.

   ```bash
DOCS_E2E_PAGE_PATHS=/docs/guides/database/functions
PLAYWRIGHT_BASE_URL=https://supabase.com pnpm e2e:docs:a11y
   ```

Expect `1 passed`, and the `::warning` annotation above in the output.

2. Confirm the scan finds that violation. Same page, now failing on
every rule.

   ```bash
A11Y_ENFORCE_ALL=1 DOCS_E2E_PAGE_PATHS=/docs/guides/database/functions
PLAYWRIGHT_BASE_URL=https://supabase.com pnpm e2e:docs:a11y
   ```

Expect `1 failed`, reporting `frame-title (serious, 4 node(s))`. Steps 1
and 2 together are the point of this PR.

3. Confirm the skipped rules stay skipped.

   ```bash
A11Y_ENFORCE_ALL=1
DOCS_E2E_PAGE_PATHS=/docs/guides/getting-started/quickstarts/nextjs
PLAYWRIGHT_BASE_URL=https://supabase.com pnpm e2e:docs:a11y
   ```

Expect `button-name (critical, 2 node(s))` and `label (critical, 2
node(s))`, and no `color-contrast`.

4. Confirm a page that does not load reports a load failure.

   ```bash
DOCS_E2E_PAGE_PATHS=/docs/guides/does-not-exist-xyz
PLAYWRIGHT_BASE_URL=https://supabase.com pnpm e2e:docs:a11y
   ```

Expect `Expected a successful response for
/docs/guides/does-not-exist-xyz, got 404`, and no axe assertion.

5. Confirm the link checker still passes alongside the a11y test.

   ```bash
DOCS_E2E_PAGE_PATHS=/docs/guides/auth/passwords
PLAYWRIGHT_BASE_URL=https://supabase.com pnpm e2e:docs
   ```

   Expect `3 passed`.

## Known gaps

- `/docs/reference/*` is not scanned. Those routes render client-side
into tens of thousands of elements, where axe exceeds its timeout and
results depend on whether the scan caught the page mid-render.
- Shared chrome is outside the article scope, so nav, sidebar, footer,
menus, and drawers are not covered.
- axe catches roughly 30-40% of WCAG issues. Keyboard navigation, focus
management, and screen reader behavior still need manual testing.

Miranda LimonczenkoandClaude Sonnet 5 52cb1c2600 feat(docs) Dynamically E2E test all docs-owned content (#48320)
Closes DOCS-1203

## Problem

The docs E2E workflow only ever tested one hardcoded page: the Next.js
quickstart. All other docs content had no E2E coverage.

## Solution

This PR expands the initial scaffolding to generalize the Next.js
quickstart tests, page runs and checks local links, to all pages
affecting Docs content:


- Add `resolveDocsScope` (`e2e/docs/utils/resolve-docs-scope.ts`) to map
changed guide and troubleshooting `.mdx` files to their `/docs/...` page
paths, and to expand changed `_partials` to every page that includes
them (including transitively, through partials nested inside other
partials). Federated guide sections (`graphql`,
`database/extensions/wrappers`, `ai/python`, `deployment/terraform`,
`deployment/ci`) and reference docs stay out of scope, and resolution is
capped at 20 pages to keep runtime bounded.
- Replace the single `quickstarts.spec.ts` test with a generic
`docs-pages.spec.ts` that loads whatever pages are resolved, asserting
each renders with an `<h1>` and that its docs-owned links resolve.
- Add `run-e2e-docs.ts` so `pnpm e2e:docs` resolves scope locally (from
commits since `origin/master`, plus staged/unstaged changes) and skips
Playwright entirely when nothing in scope changed.
- Update `.github/workflows/docs-e2e.yml` to widen the trigger paths to
all guides/troubleshooting/partials, resolve scope in a dedicated step,
skip the rest of the job when scope is empty, and accept a `page_paths`
input for manual `workflow_dispatch` runs.
- Rewrite `e2e/docs/README.md` to document the new scoping behavior, the
override envs (`DOCS_E2E_PAGE_PATHS`, `DOCS_E2E_BASE_REF`), and how CI
uses the suite.
- `pnpm e2e:docs:all` is also added to run tests on every page locally.
Good for scoping issues but should not be included in CI.

## Manual testing

Walk through the following steps to verify this works:

- [x] `pnpm e2e:docs` from repo root resolves the expected pages for a
local guide edit and can run against local dev
**Note:** Challenges with testing on local in part because of the long
lag for first page load. Recommendation to use a hosted URL is added to
docs.
- [x] Editing a shared `_partials` file resolves to every page that
includes it (including through nested partials)
- [x] `pnpm e2e:docs` exits cleanly with no Playwright run when no
in-scope files changed
- [x] `git diff --name-only ... | pnpm -C e2e/docs resolve-docs-scope`
prints the expected page list for a sample diff
- [x] Workflow run on a PR that only touches `e2e/docs`/workflow files
skips the Playwright steps
- [x] Manual `workflow_dispatch` run with `page_paths` set tests only
those pages
- [x] Run `pnpm e2e:docs:all` to run the suite on all docs content,
which takes awhile

## Next steps

After this PR merges, we have the scaffolding to add more fun tests like
a11y 😁

mode.
* Introduced `DOCS_E2E_PAGE_PATHS` (and updated base ref/base URL
behavior) to control which pages are tested.
* **Bug Fixes**
