// GROUPING_ELSE_TEOZ component while ElseTile.drawU() itself is a no-op on
// the live path. This tile owns only its row height (below) and its label.

// does the work. Never reached today — the parent special-cases ElseTile
// in its stacking loop — but kept as an explicit no-op mirroring drawU()
// rather than inheriting the AsciiBlock "not migrated" throw.
