feat: editorial review dashboard + elite-grade pilot batch (5 SKUs)

Ships the second dashboard surface — a Pattern Library + Preview Theatre — that
presents the 4-section PDP pilot batch back to Umar, compliance, and the board
in an editorial format. Adds the full data layer that drives it: 5 source-backed
per-SKU drafts at QA 100/100, 15 competitor PDP semantic extracts, PubMed
evidence packs, EFSA claims library extension, JV brand voice guide, hand-curated
product FAQs, and the Matrixify-ready CSV exports for Lewis.

+
+Ready to send: YES
+
+## Summary
+- Provider: DataForSEO
+- Endpoint: POST https://api.dataforseo.com/v3/merchant/amazon/reviews/task_post
+- Issue: 50304: This function temporarily unavailable. Please contact support for more information.
+- Credentials included: no
+- Pilot payload rows: 6
+- Live-confirmed ASINs: 6
+
+## Evidence checklist
+- **Account connection:** 20000 Ok. — Credentials/account work; issue appears endpoint-specific.
+- **Amazon Products endpoint:** 6/10 exact ASINs confirmed from live product-result evidence — Products endpoint is usable; reviews endpoint is the blocker.
+- **Amazon Reviews endpoint:** 50304: This function temporarily unavailable. Please contact support for more information. — Ask whether Merchant Amazon Reviews task_post is disabled for this account/API version/region and what replacement/restoration path exists.
+- **Pilot payload:** 6 ASIN rows at depth 10, United Kingdom / English (United Kingdom) — Payload is intentionally capped; support can reproduce with one row if needed.
+- **Official DataForSEO docs status:** endpointTemporarilyUnavailable=true; 2/3 checks passing; docs=https://docs.dataforseo.com/v3/merchant-amazon-reviews-task_post/ — Ask support whether the official temporary-unavailable note applies globally, to this account, or to the Amazon UK Reviews path specifically.
+- **Local spend guard:** 5/10 checks passing; paid posting blocked until approval gates are intentionally opened — No broad scraping or repeated retries until provider confirms endpoint availability.
+
+## Message to send
+```text
+Hello DataForSEO support,
+We can authenticate successfully and use the Merchant Amazon Products endpoint, but Merchant Amazon Reviews task creation is returning a provider-level unavailable response before any task IDs are created.
+Your public API documentation also currently marks the Amazon Reviews Task POST endpoint as temporarily unavailable.
+Endpoint: POST https://api.dataforseo.com/v3/merchant/amazon/reviews/task_post
+Response: 50304 This function temporarily unavailable. Please contact support for more information.
+Cost reported: 0
+Tasks count: 0
+The intended pilot is small: 6 Amazon UK ASINs, depth 10, location_name=United Kingdom, language_name=English (United Kingdom). The Products endpoint already returned usable ASIN evidence for those rows.
+Could you confirm whether /v3/merchant/amazon/reviews/task_post is temporarily unavailable globally, unavailable for this account, or requires a different endpoint/parameter set? If it is disabled, please advise the expected restoration path or replacement endpoint.
+No credentials are included in this packet.
+```
