Hyphen Separator
Whether the title uses a hyphen or en dash (' - ' or ' – ') as a structural separator. Distinct from em dash usage — this is the casual label-style separator, not the journalistic em dash.
Hyphen separators create a 'label: content' pattern that's popular with official political channels: 'Sen. Smith - Floor Speech on Healthcare'. It reads as formal/institutional rather than hook-driven. The em dash (—) is stylistically distinct and tracked as a separate feature.
