## What
Adds a lifecycle email sent **2 days after a user records AI consent**,
but only when that consent was given **outside of onboarding** — i.e.
more than 3 days after sign-up. This targets users who deliberately
opted into AI later (e.g. via the billing toggle / transactions banner
gated by the `AiConsentSettings` flag), not those who consented during
initial setup.
## How
- **`email:ai-consent-follow-up`** scheduled command (daily, 10:15
Europe/Madrid) selects active consents accepted exactly 2 days ago,
skips onboarding-era ones (`accepted_at <= created_at + 3 days`), and
queues a job per user.
- **`SendAiConsentFollowUpEmailJob`** sends the mailable and records a
`UserMailLog`. Dedup, locale and the queued-email plumbing all reuse the
existing drip system — **no migration**.
- Email is localised automatically via the user's `HasLocalePreference`,
like every other drip email.
## Design notes
- **Scheduled command, not a 2-day delayed job** — survives worker
restarts and respects consent revoked in the meantime.
- **Exact "2 days ago" window**, matching the existing paywall drip. If
the scheduler misses a day that cohort isn't retried; kept consistent
with the other drips on purpose.
- Copy is a first draft — open to wording tweaks.
## Tests
`tests/Feature/SendAiConsentFollowUpEmailsCommandTest.php` — 9 tests
covering the happy path, onboarding exclusion (incl. the exact-3-days
boundary), timing window, revoked consent, the disabled-drip gate,
single-send + mail log, no-resend, and locale rendering. All green, Pint
clean.
