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 1 — Try it on this Shopify customer export first
+
+**Subject:** Try it on this Shopify customer export first
+**Send:** Day 1, ~9am buyer-local-time

+Hi {{first_name}},
+
+Yesterday's email had your download. Today's email has a *file* — a synthetic Shopify customer export I built specifically to break things Klaviyo silently chokes on.
+
+→ **{{sample_file_url}}** (480 KB CSV, 2,200 rows — fully synthetic, no real customer data)
+
+What's hidden in there:
+
+- Phone numbers in 6 different formats (`(415) 555-0143`, `415.555.0143`, `4155550143`, `+44 20 7946 0958` without country field, `+1-415-555-0143 ext 12`, `415 555 0143`)
+- Email addresses with embedded zero-width spaces (looks identical to a clean email; Klaviyo treats as different addresses)
+- ~80 obvious customer duplicates (same email, different case)
+- ~40 cross-row duplicates (different email, same name + same shipping address — usually the same person ordering with two emails)
+- Shipping addresses with mixed `St.` / `Street` / `St` / `STREET` for the same street name
+- 12 customers from outside North America with country field blank
+
+Drop it into DataTools. Click **"Run all"** in the analyzer. Then run **format → dedupe → text-clean → gate** in that order.
+
+Look at the **gate report** at the end — it'll tell you exactly which rows would have broken Klaviyo, with a one-line "why" per row.
+
+If you want to see the difference: import the **raw** file to a test Klaviyo list, then import the **cleaned** file to a different test list. Compare the SMS-deliverable count. The delta is what you've been losing every month.
+
+Reply and tell me what it caught (or missed) — v1.1 detector improvements come from real-world feedback.
+
+— Michael
