The umbrella is the **intersection**, not the union: a name is on it only when both renderers
publish it under the same name and the same contract. The list is declared once, in
`PORTABLE_API` in `@asheeui/core`, and both umbrella entries are generated from it, so the two
branches cannot differ.

There are **182 names** (90 from `@asheeui/core`, 92 from the branch
renderer), plus the platform-specific `AsheeConfig` alias.

## What is not here

A name only one renderer has is not on the umbrella. It stays with the renderer that owns it,
so a shared file that imports it is a compile error on the platform that lacks it — which is
the point. The compatibility matrix (`@asheeui/core/dev`) records the classification, and the
umbrella guard (`pnpm check:umbrella`) fails when the list and the matrix disagree.

```ts
import { Breadcrumb } from "@asheeui/web";        // web-only
import { RowList, TabBar } from "@asheeui/native"; // native-only
```

The section kit is on its own subpath, because it is composition vocabulary rather than the
component inventory: `ActionGroup` and `SectionHeading` come from `asheeui/section-kit`. The
web-only `SkipLink` stays on `@asheeui/web/section-kit`.

## Adding a name

A name becomes portable in three steps: both renderers publish it, the matrix classifies it
`shared` or `shared-api`, and the name is added to `PORTABLE_API` with its `kind` and `source`.
The generator writes it into both umbrella entries, and the guard fails until the two agree.
Editing this page is not one of the steps: rerun `node scripts/build-portable-surface.mjs`.
