Miranda LimonczenkoandClaude Sonnet 5 e7d9c88cbc fix(docs): resolve remaining heading-order issues found in Pass 2 diagnostic (#48664)
## Problem

After merging [#48456](https://github.com/supabase/supabase/pull/48456)
(shared components) and
[#48459](https://github.com/supabase/supabase/pull/48459) (per-page
content fixes), a follow-up diagnostic pass found 22 remaining
heading-order violations, logged as Pass 2 in the [triage
report](https://app.notion.com/p/supabase/Playwright-E2E-Triage-Reports-3ab5004b775f81e3bc60d058fa5a02c1).
None of them were caught by the earlier fixes because they came from
places that scan didn't check: shared partials, raw HTML heading tags
written directly in MDX, and a couple of shared/interactive components
rendering hardcoded heading levels.

## Solution

- `_partials/social_provider_setup.mdx`: `#### Local development` →
`###`, matching the `##` that always precedes it on all 14 social-login
pages.
- `guides/database/functions.mdx` and
`guides/integrations/vercel-marketplace.mdx`: replaced raw `<h4>`/`<h5>`
tags with correctly-nested real headings (`### Planets`/`### People`;
`#### Deploy a Next.js app...`) — no styling workarounds needed since
they nest naturally one level below their parent section.
- `auth/quickstarts/{nextjs,react-native,react,astrojs}.mdx`: these 4
pages had no heading at all before the embedded
`_partials/api_settings.mdx` partial's own `### Get API details`
heading, so added a `## Quickstart` heading above the walkthrough to
give it a valid parent.
- `packages/ui`'s `Accordion` component: Radix's
`AccordionPrimitive.Header` renders as an unconditional `<h3>`
regardless of where the accordion is used. That's shared across Studio,
www, and design-system, not just docs, and surfaced on docs'
vendor-agnostic telemetry page. Now rendered via `asChild` onto a plain
`div` instead, since a generic accordion has no way to know what heading
level (if any) is valid in a given page.
- SQL-to-REST translator tool (`/docs/guides/api/sql-to-rest`): its
`Assumptions`/`FAQs` section labels were hardcoded `<h3>` with no `h2`
anywhere on the page. Converted to styled spans rather than promoting to
a real `<h2>`, because real h1/h2/h3 tags in this codebase force a prose
font-size that utility classes can't override — promoting the tag would
have visibly changed its size.
- `RealtimeLimitsEstimator` (embedded on both `postgres-changes` and
`benchmarks`): its 3 section headings were hardcoded `<h4>`, but the two
embedding pages need different levels (h3 vs h4) for that spot to be
valid — no single correct heading level. Converted to styled spans, same
pattern used throughout this project for components embedded at varying
heading depths.

## Manual testing

1. Check out this branch and run `pnpm dev:docs`.
2. Visit `/docs/guides/auth/social-login/auth-github` (or any other
provider page) and confirm the "Local development" callout under "Find
your callback URL" still looks and reads the same.
3. Visit `/docs/guides/database/functions` → "Returning data sets" tab
and confirm the "Planets" / "People" table captions still look the same.
4. Visit `/docs/guides/integrations/vercel-marketplace` → "Quickstart" →
"Via template" and confirm the CTA card title still looks the same.
5. Visit `/docs/guides/auth/quickstarts/nextjs` (or
react-native/react/astrojs) and confirm a "Quickstart" heading now
appears above the walkthrough, and "Get API details" still renders
correctly further down.
6. Run `pnpm dev:design-system` and open
`/design-system/docs/components/accordion` — expand/collapse an item and
confirm it still animates and looks identical; inspect the DOM and
confirm the trigger's wrapper is a `div`, not an `h3`.
7. Visit `/docs/guides/api/sql-to-rest`, translate any query, and
confirm the "Assumptions"/"FAQs" section labels still look the same.
8. Visit `/docs/guides/realtime/postgres-changes` and
`/docs/guides/realtime/benchmarks`, scroll to the connection-limits
calculator, and confirm its section labels still look the same on both
pages.
9. (Optional, for a full re-check) Run `pnpm e2e:docs:a11y --all`
against a deployed preview of this branch — only `/docs/guides/cli`
(pre-existing 404, unrelated to headings) should fail; every other page
should pass.

Verified with a full Playwright run against a real preview deployment:
**756 passed, 1 failed** (`/docs/guides/cli`, the pre-existing unrelated
404). Zero heading-order violations remain.

Supabase UI Patterns

This package should be used for components which are built using NPM libraries (react-markdown, reactflow for example), which make no sense to be included in all apps. It should also be used for components which are constructed using various components from the ui package.

This package does not have a barrel file - each component has to be imported from its index (ui-patterns/PrivacySettings, for example). This is intentional so that adding a new component which is used only in 1 or 2 apps doesn't burden the rest of the apps.
