What/Why?

Closes BON-22. The issue said the demo tests mock @camp.dev/bones/react and so can't see skeleton-markup regressions. The mocks turned out to be dead, and the real gap was that no test rendered anything under forceBones.

The mocks never ran. Every vi.mock("bones", …) targets the module id bones, the dependency name in the initial commit. PR #29 renamed the package and pointed the components at @camp.dev/bones/react, and apps/demo/vite.config.ts has no bones alias, so the calls matched nothing. The suite has rendered through the real package since PR #29. A scratch test confirmed it: with the mock in place, <PokemonCard pokemon={forceBones} /> still emitted [data-bone] from the real bone(). This PR deletes bonesMockFactory, bonesWithDataMockFactory, and the fourteen vi.mock("bones") lines.

Every skeleton-bearing component now has a forceBones test. Each component that calls createBones and renders a skeleton gets a test that counts [data-bone] elements exactly. LocationsPanel returns null while pending, so it has nothing to count. DexEntriesPanel and MovesPanel had no test file at all before this PR. Where the component uses repeat or lines, the count pins the slot count, so a composite that passes undefined instead of forceBones to a child fails the test. The theming and animations demos now require [data-bone] on the cards they already render. The multi-line-text, forced-skeletons, and Suspense demos render their fallback paths (the Suspense test uses a vi.hoisted flag to hand PokemonGrid a never-resolving promise).

One real bug fell out. PokemonDetailView passed stat={item} to StatBar inside repeat, so under forceBones its six stat rows rendered with no bones. It now forwards item ?? forceBones, the same fix PokemonGrid got in PR #47. Nothing in the app mounts PokemonDetailView today, so no page changes.

No changeset: apps/demo is private.

Testing

  • cd apps/demo && vp test --run: 95 passed in 23 files (76 in 21 before). The two new PokemonDetailView tests were red before the one-line fix (9 bones instead of 27, 0 in the stats section) and green after.
  • cd apps/demo && vp check: 0 errors. The one warning is the pre-existing triple-slash reference in next-env.d.ts.

Summary by CodeRabbit

  • Bug Fixes

    • Improved skeleton rendering for Pokémon detail statistics when data is unavailable.
    • Ensured forced loading states display consistently across demo components.
  • Tests

    • Expanded coverage for loading, pending-data, and skeleton states across cards, panels, grids, heroes, and detail views.
    • Added validation for rendered content, skeleton counts, placeholders, and grouped entries.
    • Replaced brittle test stubs with realistic skeleton behavior checks.
    • Added coverage for partially loaded content and pending data scenarios.

The demo tests never mocked the package. Every `vi.mock("bones", …)`
targeted the module id `bones`, the dependency name from the initial
commit. PR #29 renamed the package to `@camp.dev/bones` and pointed the
components at `@camp.dev/bones/react`, so the mocks stopped matching
anything and the suite has rendered through the real package since.

Delete the dead `bonesMockFactory` and `bonesWithDataMockFactory` and
the fourteen `vi.mock("bones")` lines that named them.

Add a `forceBones` test to each of the nine components that call
`createBones`. Each test counts `[data-bone]` elements, and where the
component uses `repeat` or `lines`, the count pins the slot count too.
The wrapper demos now require `[data-bone]` on the skeleton cards they
already render, and the Suspense and toggle demos render their fallback
paths.

The new `PokemonDetailView` test failed: it passed `stat={item}` to
`StatBar`, so under `forceBones` six stat rows rendered without bones.
Forward `item ?? forceBones`, the same fix the grid got in PR #47.

Review found two skeleton-bearing components with no test file:
`DexEntriesPanel` and `MovesPanel`. Add both. The `MovesPanel` test
also pins the hand-off to `MovesInteractive` when only `moveDetails`
is pending, the one composite boundary the first commit left unguarded.

Also from review: select the Base Stats section by its heading instead
of by index, reset the Suspense demo's pending flag in `afterEach`,
pin the grid to 48 bones, and drop the two `next/image` mocks that the
first commit added without needing them.

📝 Walkthrough

Walkthrough

The demo tests now use the real bones implementation. They add coverage for forced and pending skeleton states, tighten skeleton selectors and counts, and update PokemonDetailView to propagate forceBones to stat bars.

PokemonDetailView passes forceBones to missing stat entries. Tests cover full and partial skeleton states and count only bone-marked images.

- Around line 26-27: Update the InfoCard test to explicitly assert that the
“Base Exp” label is rendered in addition to “Catch Rate”; retain the existing
bone-element assertion, since the test must verify both labels rather than infer
visibility from skeleton count.
