feat: Tier B operator scaffolding — bundle, copy SoT, posts, emails

Pick up and finish yesterday's cut-off Tier B pass.

- build/: PyInstaller scaffold (datatools.spec + launcher.py +
  hook-streamlit.py + README) — folder-mode bundle, locked
  127.0.0.1, per-OS recipe
- marketing/COPY.md: single source of truth for every customer-facing
  string — landing H1/sub/CTAs, demo CTAs, email subjects, Gumroad
  listing, banned phrases
- marketing/community-posts/: 9 drafts (3 posts × 3 niches:
  bookkeeper, revops, shopify-pet) — story / tip / soft-offer
- marketing/emails/: 18 drafts (Gumroad delivery + 5-touch
  onboarding × 3 niches), per-niche segmentation guidance
- docs/NEXT-STEPS.md: flip 2.2 / 2.4 / 3.1 / 3.4 to done with
  pointers to the new assets; add Phase 0 inventory rows
- .gitignore: narrow `build/` ignore so PyInstaller spec + launcher
  + hooks get tracked, only generated artifacts (build/build/,
  build/__pycache__/, build/dist/) stay ignored

+# Shopify-pet · Day 7 — Run it before every Klaviyo sync
+
+**Subject:** Run it before every Klaviyo sync
+**Send:** Day 7
+**Goal:** reframe from one-off tool to per-sync workflow
+
+---
+
+Hi {{first_name}},
+
+A week in. By now you've probably run DataTools on a real customer export once or twice and seen the cleanup catch things you'd been losing in Klaviyo for months.
+
+The thing that turns DataTools into a recurring win instead of a one-off purchase: **run it before every sync, not just the first time.**
+
+The pattern that works for most stores:
+
+**1. Pick a cadence.** Most stores I talk to do this monthly; high-volume stores do it weekly. The cadence should match your "I'm planning a campaign" rhythm.
+
+**2. The Sunday-morning ritual:**
+- Pull a fresh customer export from Shopify (Customers > Export > "All customers")
+- Drop into DataTools
+- Run the pipeline (analyzer → format → text-clean → dedupe → gate)
+- Review the gate quarantine file (typically 0.5-2% of rows)
+- Push the cleaned CSV to Klaviyo (their CSV import or via their API)
+
+**3. Save your settings as a preset.** The "Save settings" button writes a `.datatools-preset.json`. Keep it in your store's Drive / Notion / wherever your shop docs live. Next month, load preset, run pipeline, done in 4 minutes.
+
+**4. After 3 months, retune the preset.** Look at your manual-review queue across the 3 runs. If you're consistently approving 0.86-confidence merges, drop the auto-merge threshold to 0.85. If you're rejecting 0.92 merges, raise it to 0.94. The preset improves with use.
+
+The store owners doing this monthly tell me their open rates go up 8-15% in the first 90 days — not from new content, just from the email actually reaching the inbox.
+
+If you want, reply with a sanitized export and I'll suggest a starting preset for your store — happy to do this for the first 50 buyers.
+
+— Michael
