bright lines
Spectral emission features
Bright lines are clear, unambiguous boundaries or rules that leave no room for interpretation.
In law, a bright-line rule provides a definitive standard: The Constitution draws a bright line at age thirty-five for presidential eligibility.
The term contrasts with fuzzy or case-by-case standards that require judgment.
Bright lines offer predictability but may sacrifice nuance.
