- campaign_helpers.py: extract the branded Listmonk HTML helpers (hdr/flagbar/
stats/cta/footer/P/UL/etc.) + create_campaign() from create_campaigns.py into
a side-effect-free shared module; create_campaign() now takes an altbody so
every campaign ships a plaintext alternative (deliverability).
- create_crtc_usf_campaign.py: build the one-off CRTC email hooked on the Q3
2026 USF factor (38.8%, +1.8pts, eff Jul 1), with a $200-off CANADA200 banner
(expires Fri 23:59 ET, CTA links carry ?code= for auto-apply), the full US
carrier burden vs Canada advantage, BC/ON incorporation, and a hosted
carrier-guide PDF download. Creates a DRAFT only; sending stays manual.
