// Test files that render through the ComponentRegistry and therefore need the
// heavy `vitest.setup.dom.tsx` (the four side-effect package imports + widget
// re-registrations). They run in the `dom-heavy` project; every other DOM test
// gets the trimmed `vitest.setup.dom-light.tsx` default.
//
// This list was derived empirically: run the whole `dom` project under the
// light setup and every file here is one that failed (e.g. "page:card not
// registered", or an element that never rendered). It is a small minority
// (~20 of ~310 DOM files) — the other ~290 never touch the registry and used
// to pay ~3.3s/file of setup for nothing.
//
// If a NEW test renders a schema / page:* / dashboard / grid widget and fails
// with "<type> not registered", add it here. Misfiling is self-correcting, not
// silent: a heavy test left out of this list lands in the light `dom` project
// and fails loudly in CI (it can never be skipped), so coverage cannot be lost
// — only a red build that points at the fix.

    //
    // - `unit`: pure-logic *.test.ts in node env + vitest.setup.base.ts only.
    // - `dom`: React tests in happy-dom with the LIGHT setup — jsdom polyfills,
    //   jest-dom and RTL cleanup, but none of the @object-ui/components / fields
    //   / plugin-dashboard / plugin-grid graphs.
    // - `dom-heavy`: the ~20 `heavyDomTests` that render through the
    //   ComponentRegistry, with the full `vitest.setup.dom.tsx`.
    //
    // Why the split: with `isolate: true` every setup import re-executes per
    // file. The old single DOM setup pulled the four heavy package graphs into
    // every one of ~300 DOM files (~3.3s/file of setup) even though ~290 never
    // touch the registry — a CI run spent ~20 min cumulative in setup for ~3
    // min of actual tests. Restricting that graph to the files that need it
    // leaves the common case paying only the light setup.
    //
    // (The former `environmentMatchGlobs` split silently stopped working on
    // Vitest 4 — the option was removed — so every file was paying happy-dom
    // + full DOM setup regardless of suffix.)
    //
    // Absolute paths for file entries so the project list resolves the same
    // regardless of the cwd vitest is launched from (`turbo run test` runs
    // each package's `vitest run` from that package's directory).
