+// gen-deal-brief.mjs — Boomer "Deal of the Day" audio brief (REPOINT feature #3, Steve-approved 2026-08-06).
+// Picks the top deal by amount, composes a FACTUAL ~450-char script (reusing verified deal fields incl. the
+// new `acquirer`), synthesizes it in Boomer's cloned voice via ElevenLabs, caches the mp3 + metadata.
+//
+// SPEND GUARD (the memo's key guardrail): regenerates ONLY when the top deal CHANGES (dedupe on deal id) —
+// never per-cron — so daily cost stays ~$0.15, not ~$10. `DRY_RUN=1` composes the script + writes metadata
+// with NO TTS call ($0). `--force` overrides the dedupe.
+//
+// Boomer is the on-air PERSONA ("This is Boom…") — never "Bloom" in any customer-facing text. The script is
+// factual-only (no editorializing) so an auto-published brief can't misstate a deal.
