// TestEngineStartingIndentOffsetsBreakDecision verifies the
// StartingColumn option charges its column count against the printWidth
// budget while BaseIndent controls where continuation lines align.
//
// The authored seven-column foo bar group has only five columns left when
// StartingColumn is five and PrintWidth is ten. Its first fragment receives
// no generated indentation; BaseIndent two independently supplies the two
// spaces on the broken continuation. This direct case uses no AST reflow.
//
// @evidence contracts/testing.md#behavioral-verification Print must break foo bar and align bar to BaseIndent two when StartingColumn five consumes the width-ten budget.
// @evidence contracts/testing.md#independent-expectations Seven flat columns exceed the five remaining; the literal two-space continuation follows BaseIndent independently.
// @evidence contracts/testing.md#distinguishing-cases Nonzero starting geometry distinguishes this from the same doc fitting at column zero.
// @evidence contracts/testing.md#execution-ownership TestEngineStartingIndentOffsetsBreakDecision is one Go unit entry that renders a literal Group with Print under StartingColumn 5, BaseIndent 2 and PrintWidth 10 in-process; it parses no source and installs, builds and launches nothing.
