## Summary
Landing page copy and social proof around AI, made consistent with our
privacy stance.
- **Clarify AI as a privacy-respecting feature.** Name AI explicitly
where transactions are auto-categorized, replace the contradictory "no
AI snooping" line with an "our own AI" framing, and add an FAQ stating
the AI serves you and never trains on, sells, or shares your data.
- **Add six testimonials**, four of which highlight AI and automation
(AI categorization that learns from corrections, automatic bank sync,
the privacy framing of our own AI, and CSV auto-mapping). The other two
cover the all-in-one-place and clean-UI experience.
## Notes
- All new strings have matching `lang/es.json` translations;
`LocalizationTest` passes.
- New testimonials use placeholder gravatar hashes that 404 and fall
back to the generated `Facehash` avatar (no real photo needed).
## Test plan
- [x] `php artisan test tests/Feature/LocalizationTest.php`
- [x] Prettier formatting
