gp-marketing

Add a new Sanity page-builder block (a reusable section the marketing team can drag onto pages). Use when the user wants a new component, block, or section type on the marketing site that does not already exist. Runs the scaffolding generator so no wiring is missed, then customizes and verifies it.

Open a PR on gp-marketing following GoodParty conventions and drive it to all-green — the delegate-reviewer bot approves and every CI check passes. Use when the user says "open a PR", "ship this", "ship it", "create a PR", or otherwise wants their change turned into an approved PR.
