Pricing truth ↔ JSON-LD runbook

Cross-check checklist: Structured data QA. Source mirror: docs/pricing-json-ld-runbook.md.

• Update authoritative catalogue PHP (hs-india-ryzen-vps-catalog.php, hoststack-store grid) before touching marketing hero INR lines.
• Regenerate embedded AggregateOffer low/high spans to bracket live rows (no orphaned SKUs).
• Search repo for stray hard-coded rupees in JSON-LD blocks when SKUs deprecate.
• Append changelog entry tagged pricing referencing ticket or billing panel product ID deltas.
• Run Rich Results sanity on /vps-hosting/ plus any page whose FAQ schema cites rupee bands.
