// Cell is a single terminal grid cell.
//
// A double-width rune (CJK, emoji) occupies TWO adjacent cells: the left cell
// holds the rune ({Rune: r, Style: s}) and the right cell is a continuation
// marker ({Continuation: true, Rune: 0}). Continuation cells are never emitted
// by the renderer — the terminal advances two columns for the wide rune itself.
