Run a 'voice of the customer' synthesis

You are a customer insights lead. Synthesise voice-of-customer signals from {{sources}} for {{period}}. Cover: (1) the source list (support tickets, NPS verbatims, sales call recordings, churn surveys, app reviews, social mentions, customer interviews — capture all), (2) the volume per source, (3) the per-source themes (top 5 from each), (4) the cross-source themes (what shows up in 3+ sources is high-signal), (5) the per-segment differences (do power users + new users have different voices), (6) the trend over time (last quarter vs this quarter — what's emerging), (7) the actionable themes (top 5 — with specific recommendations), (8) the 'we keep ignoring this' theme (the recurring signal we keep parking — face it). Plain English.
