+Direction-aware icons (the forward chevrons on menu rows, the log-out arrow, and the previous/next arrows in paginated lists) now mirror horizontally when rendered under an ancestor with `dir="rtl"`.

 - **Shared playground state.** `DocsViewer` wraps each overview in a `PlaygroundProvider` (`PlaygroundContext.tsx`), keyed by slug and seeded from the component's `meta` via `getModuleBySlug`. It owns the knob values (props). The `<Preview>` and the interactive `<PropTable>` both read/write this single context, so editing a prop in the table updates the preview above it.
 
 - **Every story renders inside `MosaicProvider`.** `StoryPreview` (the MDX `<Preview>`) renders a named story with the playground's knob values as props and exposes a Reset button. `StoryEmbed` (the MDX `<Story>`) renders a single static variation with default knob values and no controls.
+  - The header's **RTL** switch (`DirectionToggle`, state in `DirectionProvider`) sets `dir` on `<html>`. It has to sit that high because popover and menu popups portal to `<body>`, so a `dir` on the preview container would never reach them; swingset's own chrome flips along with the story.
 
 - **The prop table is the knob surface.** `PropTable` (MDX `<PropTable>`) derives rows from `meta.styles._variants`/`_defaultVariants`, then appends the `className` + `style` escape-hatch rows every Mosaic component accepts. Each variant row renders a `KnobControl` in its **Value** column, seeded with the prop's default and bound to the playground context. The escape-hatch rows and `extra` stay static.
