+# Component rendering review
+
+## Confirmed defects and plan
+
+Baseline: PR #32 at `9c671aca473e2b6e38ea03f2cd74177074fa750d`.
+Reviewed the rendered docs at 1280, 768, 390, and 320px before changing component code.
+Compared existing bevels, surfaces, typography, and control density with WorkbenchOS.
+
+| Finding                                                        | Baseline evidence                                                                                                    | Fix                                                                                                                                                        |
+| -------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| SegmentedMeter overstates partial capacity                     | At 320px, a 50/100 value fills the entire 257px inner track. Zero-value segments leave a 1px divider.                | Size segments against the resolved maximum, leave unused capacity visible, and omit zero-value spans. Use an inset divider that does not consume capacity. |
+| Tabs ignore vertical orientation and overflow with long labels | Vertical tabs render horizontally. A 280px label escapes 259px of available content, widening the document to 324px. | Add scoped orientation layout and constrain labels. Preserve nested tab orientation and keyboard handling.                                                 |
+| Disabled tabs look enabled                                     | Base UI sets data-disabled and aria-disabled, while the CSS only matches native :disabled.                           | Match the actual state attribute for disabled styling and hover exclusion.                                                                                 |
+| Toolbar groups overflow narrow containers                      | A button and input produce a 301px scroll width inside a 204–216px toolbar.                                          | Let groups wrap and controls shrink within their toolbar; stack vertical groups.                                                                           |
+
+The plan was to reproduce these defects, make scoped fixes, then check rendered results,
+keyboard behavior, neighboring controls, package output, and responsive containment.
+The existing maximum normalization, numeric ARIA values, public props, and exports remain
+unchanged. Disabled tabs remain focusable without becoming selected.
+
+## Docs re-review and correction
+
+The first implementation also added white inset tab panels and prominent edge-case demos.
+Those were poor documentation choices: artificial labels and placeholder content added
+clutter, while the inset surface made static content resemble an input. Docs copy alone
+was not sufficient justification for changing every consumer's panel appearance.

Restore the original undecorated panel and horizontal spacing. Keep one existing example, mark Advanced disabled, and correct the intro. Retain the functional orientation, wrapping, disabled, and focus fixes. |
+| Meter                                                                         | Remove the added capacity comparison and empty-track demo. Show partial capacity in the existing segmented-meter example: 34 of 40 miles surveyed. Keep the ordinary Meter example for its distinct API.                                                                                     |

Keep the existing toolbar with one short note about wrapping and orientation.                                                                                                                                                                    |

They demonstrate useful behavior without adding another demo card.                                                                                                                                          |
+| Select, RadioGroup, Slider, Accordion, ToggleGroup, Empty, and overlay titles | Keep the brief API guidance and changes inside existing examples. These explain callback types, slot content, or precedence without repeating the component.                                                                                                                                 |
+
+Move the synthetic meter, tab, and toolbar cases to `tests/browser/fixtures/rendering.tsx`.
+The browser tests load them through a development-only HTML entry under `docs/__tests__`.
+The main docs do not import them, and the production build still uses only `index.html`.
+Remove the superseded screenshot gallery so it does not present the reverted design as
+an approved result. The original captures remain in the earlier PR commit.
+
+## Validation
+
+- Inspected the simplified docs at 1280, 768, 390, and 320px: tabs, toolbar, meters,
+  fields, selection controls, grouped controls, application patterns, and overlays.
+  The public docs have no horizontal overflow. Tab selection still works.
+- `npm run check`: formatting, lint, typecheck, and all 54 unit tests pass.
+- `npm run test:browser`: all 23 tests pass, including 12 isolated rendering/interaction
+  regressions and the existing public-docs, window, and overlay checks.
+- `npm run build`, `npm run build:docs`, and `npm run pack:check`: pass.
+- A separate clean docs build under `/tmp/grayui-simplified-docs-build` confirms that
+  neither the development entry nor the synthetic fixture content ships in production.
+  The managed checkout retained unused assets from a previous build; the generated
+  index references the current assets.
+- Browser coverage is Chromium only, using the temporary executable described in the
+  TypeScript review. No dependency was added. npm emits the environment's existing
+  unknown `http-proxy` configuration warning.

+# TypeScript and component API review

+Reviewed all 43 component modules, the public barrel, declaration build, package exports,
+fieldset context, store shims, docs examples, and validation configuration against
+`c56271ce216bbd3d7603359869ad1c23ee127030` (0.6.2). The compiler already enables `strict`,
+`noUncheckedIndexedAccess`, and `exactOptionalPropertyTypes`; the actionable type defects

+| Slider, Accordion, and ToggleGroup erase generic information             | A scalar Slider callback receives a number/array union; Accordion loses its item type; ToggleGroup widens literal unions to `string`.                                    | Carry the primitive type parameter through each wrapper.

+| Switch ignores greyUI's disabled fieldset context                        | A switch inside nested disabled fieldsets fires its callback and lacks disabled state on the control and label. The docs reproduction fails at all four viewport widths. | Resolve inherited disabled state through the same context used by Checkbox.

+| Package checks do not compile consumer contracts                         | The original declaration build and package audit pass despite the API type defects above.                                                                                | Compile the same consumer examples against source paths during `typecheck` and real root/subpath package exports during `pack:check`, with `skipLibCheck: false` for published declarations.                                                                 |
+| Browser output contaminates subsequent checks                            | `npm run check` attempts to format generated Playwright JSON and trace HTML after browser tests.                                                                         | Ignore `test-results/` and `playwright-report/`, then run the normal checks after browser validation.                                                                                                                                                        |
+
+Type parameter preservation follows the [TypeScript generics guidance](https://www.typescriptlang.org/docs/handbook/2/generics.html).
+The Autocomplete rendering change follows React's rule to
+[let React call components through JSX](https://react.dev/reference/rules/react-calls-components-and-hooks#never-call-component-functions-directly).
+The existing, documented assertion bridging Base UI's overloads remains confined to that
+implementation boundary.
+
+## Validation
+
+- Baseline `npm run check`: 51 tests pass. New consumer fixtures fail on the original
+  value/callback/title/grouped-item contracts; the Empty and disabled Switch regressions
+  fail before implementation changes.
+- Final `npm run check`: formatting, lint, TypeScript, and 54 tests pass.
+- `npm run build`, `npm run build:docs`, and `npm run pack:check` pass. Package validation
+  covers strict consumer declaration checking, entrypoint existence, SSR imports, runtime
+  externals, and bundle budgets.
+- Browser suite: 11 tests pass, including existing window and overlay regressions and new
+  component API flows at 1280, 768, 390, and 320 pixels.
+- Reviewed rendered captures of grouped controls, open suggestions, Empty children, and a
+  dialog with a React title. Compared original and fixed component code using the updated
+  docs examples. The original code reproduces the missing disabled Switch state at all
+  four widths; the fixed examples and document remain contained.
+
+The interactive cloud browser could not open localhost and the standard Playwright browser
+CDN timed out. Local browser tests used a temporary npm-distributed Chromium executable via
+`PLAYWRIGHT_EXECUTABLE_PATH`; no browser dependency or executable is added to the package.
+Validation emitted environment warnings about npm's `http-proxy` setting and conflicting
+color-output variables. Cross-browser and assistive-technology testing were not performed.
+
+## Compatibility notes
+
+Select and RadioGroup now reject non-string selections that cannot match their string-valued
+options. JSX Select usage also rejects mismatched single and multiple value shapes. For a
+precisely typed prop bag, use `SelectProps<false>` or `SelectProps<true>`; the unparameterized
+type continues to allow both modes. Existing string-valued controls, explicit Empty contents,
+flat Autocomplete items, and popup string titles remain supported.
