+// Width reports the number of terminal cells the rendered string s occupies. It
+// delegates to lipgloss v2's width measurement, which strips ANSI escape
+// sequences and counts East Asian wide / fullwidth runes (CJK, emoji) as two
+// columns. This is the single width primitive the TUI and REPL layers style
+// through (per the tui-agent SPEC), so alignment stays consistent across the
+// codebase instead of each caller hand-rolling its own East-Asian-width table.
+//
+// For multi-line input, Width returns the width of the widest line (lipgloss
+// measures the bounding box), matching how the renderer lays text out.
