## Summary
- Adds an inline email capture form on the landing page when
`HIDE_AUTH_BUTTONS=true`, replacing the previous CTA buttons
- Each signup gets a queue position (starting at #500), a unique
referral link, and a welcome email from `victor@whisper.money`
- Referring 10 people via the personal link moves the referrer 10
positions forward in the queue (floor: 1), triggering a notification
email
- Full Spanish localisation for all UI strings and email copy; `locale`
is stored on each lead so emails are sent in the lead's own language
- 14 feature tests covering all waitlist behaviour (positions,
referrals, emails, thank-you page)
## How to activate
Set `HIDE_AUTH_BUTTONS=true` in `.env`. The waitlist form and thank-you
page are completely dormant otherwise.
