Phase 1: tier demo landing pages, CRM schema, playbooks

- templates/landing: two self-contained demos (Tier A barbershop / Google stack,
  Tier B physio / self-hosted) + chooser page
- sheets/SCHEMA.md: Google Sheets CRM workbook spec
- playbooks: per-client setup checklists for both tiers
- README + .gitignore
- Demos avoid unverifiable claims (no "DSGVO-konform", no "Ende-zu-Ende")

+# Playbook — Tier A (Google stack)
+
+For casual businesses with no data-residency concern. Infra cost ≈ €0. You charge for setup +
+ongoing management. Target build time: ~half a day per client.
+
+## When to pick Tier A
+- Barber, café, salon, food truck, small retail, trades — public-facing, no sensitive data.
+- Client wants cheapest option and is fine with Google handling data.
+
+## Setup checklist
+1. **Client Google account** — create a fresh free Google account for the client (or use theirs).
+2. **Landing page** — clone `templates/landing/demo-tier-a/`, rebrand (name, colours, copy,
+   services, hours, photos). Deploy to a free always-on static host (e.g. Cloudflare Pages).
+3. **Domain** — connect the client's domain (or a `.de` you register and bill through).
+4. **Booking** — set up Google Calendar **Appointment Schedule**; embed the booking link/button
+   on the page (replace the demo booking card).
+5. **Lead capture** — create a Google Form *or* point the page form at the n8n lead webhook
+   (preferred — so leads land in the CRM, not just Google).
+6. **Reception** — Gmail for the business; set a signature + canned replies.
+7. **Google Business Profile** — claim/verify so they show up on Maps & Search.
+8. **CRM** — add a `Clients` row (tier = A, services, monthly_fee, renewal_date, vault_ref).
+9. **Handover** — share logins via Vaultwarden; record only the `vault_ref` in the sheet.
+
+## What to charge (suggestion)
+- One-off setup: €250–600 depending on pages/content.
+- Monthly management (updates, hosting oversight, booking support): €20–40.
+
+## Recurring tasks (automated by n8n where possible)
+- Renewal reminder (from `renewal_date`).
+- Monthly "anything to update?" nudge.
+- Lead notifications to the owner.
