agency-multi-brand-packlisted

# Agency multi-brand pack Run generations for N retainer clients in one coordinated pass — each client's output strictly namespaced, each job gated by that client's brand rules, every run audit-ready for legal and billing. **N clients × M templates per client → one batch, zero cross-contamination.** For agencies running weekly/monthly creative cycles across a client portfolio. ## When to Use - Weekly/monthly retainer refresh across multiple retainer clients - Portfolio-wide seasonal re-skin (e.g. holiday refresh for all 8 retainer brands in one batch) - Multi-client pitch week where each pitch needs its own branded mockup set - Audit-ready production runs where finance/legal need a per-client spend breakdown - Any agency workflow where "run the same pipeline for every client, with their rules" is the task **Do not use for** single-client deep-production work — drop to `agency-pitch-mockups` or a client-specific workflow. Multi-brand is for portfolio parallelism. ## Prerequisites Ask the user (one message): 1. **Client list** — slugs of clients in scope (e.g. `acme-fintech`, `zest-retail`, `nova-travel`). Each must have a locked `brand-system.json`. 2. **Template set per client** — same across all clients (hero + 3 social + OG) or does each client have a different deliverable? 3. **This week's theme / brief** — one brief that gets re-expressed per client (e.g. "Q2 product refresh") or fully independent briefs per client? 4. **Output destination** — Drive folder per cli
