+
+/// A thin wrapper around a single text line captured
+/// by a block.
+///
+/// When a block executes the command it captures stdout
+/// and splits each line into a cell. Each cell is then
+/// laid out horizontally respecting the order.
+///
+/// Besides the underlying text value, a cell holds an
+/// highlighted status that, if true, applies the special
+/// background color defined in `Config.swift`.
+/// You can set the highlight at runtime by prefixing the
+/// text line with the special notation `!!`.
+///
+/// E.g: `echo "!! $(date "+%a %d, %H:%M:%S") "`
+///
+/// Highlight can have multiple use cases, but it was
+/// imagined specifically for distinguishing a single cell
+/// within a group. For example when you want to show which
+/// workspace is currently active.
+struct Cell: RawRepresentable, Identifiable {
+	/// Stable identity for SwiftUI diffing.
+	let id = UUID()
+
+	/// The represented text content.
+	let rawValue: String
+
+	/// Whether the cell is highlighted or not.
+	let highlighted: Bool
+
+	/// The background color derived from the highlighted state.
+	///
+	/// Returns `Config.highlight` when the cell is highlighted,
+	/// otherwise `.clear` so the underlying bar background
+   /// shows through.
