Minor Changes

• #​7348 3c160b2 Thanks @​mattcosta7! - Add currentWidth and onResizeEnd props to PageLayout.Pane for controlled resizable width

  The PageLayout.Pane component now supports controlled width:

  • onResizeEnd — callback fired when a resize operation ends (pointer release or keyboard key up). Replaces localStorage persistence. Requires currentWidth.
  • currentWidth — sets the current displayed width in pixels (number | undefined). Pass undefined when the persisted value hasn't loaded yet. Requires onResizeEnd.

  Both props must be provided together (enforced by TypeScript). resizable remains a plain boolean prop.

  These props are only meaningful when resizable={true} — without it, no drag handle renders so onResizeEnd never fires.

  New export:

  • defaultPaneWidth — Record of preset width values: {small: 256, medium: 296, large: 320}

  Example usage:

  import {PageLayout, defaultPaneWidth} from '@​primer/react'
  
  // Default behavior (unchanged) — localStorage persistence
  <PageLayout.Pane resizable />
  
  // Controlled width with custom persistence
  const [width, setWidth] = useState(defaultPaneWidth.medium)
  <PageLayout.Pane
    resizable
    currentWidth={width}
    onResizeEnd={(newWidth) => {
      setWidth(newWidth)
      myStorage.save('pane-width', newWidth)
    }}
  />
  
  // Async load — pass undefined until value is fetched
  <PageLayout.Pane
    resizable
    currentWidth={savedWidth ?? undefined}
    onResizeEnd={handleResizeEnd}
  />
