The cassettes cannot reach these branches. Every fixture email is
already lowercase, so nothing exercised the trim-and-lowercase that is
the Google Analytics driver's whole merge key; likewise the Dotfile role
casing and the Segment role dedup and case-insensitive owner match.
The Dotfile and Square tests never asserted CreatedAt, which
parseRFC3339Ptr silently nils on any format mismatch — both cassettes
carry usable timestamps, so a dropped field looked like a clean pass.
Also gives the Square OAuth variables their own comment in the example
env file; they sat under the Google Analytics one.
