"""Phase 6A — editorial_text slot on the empty_state partial.

The shared empty_state partial supports a 3-sentence editorial paragraph
that downstream RIMS templates use for the system/filter/constraint voice
([[project_rims_t4_editorial_2026_05_17]]). The slot is optional; callers
that pass only heading + subtext must render unchanged.
