const docs = `### Overview
Render a code diff with OpenCode styling using the Pierre diff engine.
Pair with \`DiffChanges\` for summary counts.
Use \`LineComment\` or external UI for annotation workflows.
### API
- Required: \`before\` and \`after\` file contents (name + contents).
- Optional: \`diffStyle\` ("unified" | "split"), \`annotations\`, \`selectedLines\`, \`commentedLines\`.
- Optional interaction: \`enableLineSelection\`, \`onLineSelectionEnd\`.
- Passes through Pierre FileDiff options (see component source).
### Variants and states
- Unified and split diff styles.
- Optional line selection + commented line highlighting.
### Behavior
- Re-renders when \`before\`/\`after\` or diff options change.
- Line selection uses mouse drag/selection when enabled.
### Accessibility
- TODO: confirm keyboard behavior from the Pierre diff engine.
- Provide surrounding labels or headings when used as a standalone view.
### Theming/tokens
- Uses \`data-component="diff"\` and Pierre CSS variables from \`styleVariables\`.
- Colors derive from theme tokens (diff add/delete, background, text).
