Overview

StatusBar is a compact informational strip designed to sit at the bottom of an application window, mirroring the pattern found in code editors, terminals, and desktop applications. It renders at a fixed 28px height with a monospace font (`--font-mono`) and muted text color, providing an unobtrusive surface for status indicators, cursor positions, encoding info, and connection states. The component uses a three-region flexbox layout with named slots: `start` (flex-shrink: 0, anchored to the leading edge), default (centered, flex: 1), and `end` (flex-shrink: 0, anchored to the trailing edge via margin-left: auto). This pattern ensures the left and right indicators stay pinned to their edges while center content fills the remaining space. The `position` prop controls whether the status bar flows with the page layout (`static`, the default) or sticks to the bottom of the viewport (`fixed`). Fixed positioning sets `bottom: 0`, `left: 0`, `right: 0` with a z-index of 100, making the bar persistent across scrolling. The bar renders with `role="status"` for screen reader announcements of dynamic content changes.

Guidelines

When to use

Use StatusBar for editor-style applications that need persistent status indicators
Place cursor position, line numbers, or encoding info in the prefix slot
Put connection status, sync state, or version info in the suffix slot
Use the center slot for transient messages like "Saved" or "Building..."
Set position="fixed" when the status bar should persist during scrolling

When not to use

Do not use StatusBar as a primary navigation bar — use TopBar or Toolbar instead
Do not place interactive buttons or form controls in the status bar — keep it informational
Do not set position="fixed" in layouts where AppShell already manages the bottom edge
Do not override the 28px height — the compact size is intentional for information density
Do not use StatusBar for toast-style notifications — use Toast or Alert for user-facing messages
