What this releases

Updates to the ad landing page (four commits, five changes):

1. New address. The page moves from /start to /website-landing-page (rupee and dollar copies). /start redirects there and keeps the ad's utm_ and click tags, so any early link still works. Still noindex, still out of the sitemap.
2. Links followed. The page is noindex only: the meta tag becomes noindex, follow once the site is live and the header is X-Robots-Tag: noindex. It no longer says nofollow. robots.txt stays open so ad reviewers can load it.
3. Form buttons. "Pay now" and "Talk to us" sit side by side at equal size, each with a round icon chip at the right edge (arrow, WhatsApp) and the label centred beside it. "Talk to us" has a light copper fill so it reads as a button. They stack only on the narrowest phones. The price card's pay button matches, through an optional centred label on the shared arrow button (other uses of it are unchanged).
4. Country code dropdown. The mobile field has a custom dropdown (34 countries, India first and the default on the rupee page, the browser's country on the dollar page). Keyboard, type-ahead and screen reader support. The form sends the dial code and number together; India takes a 10-digit Indian mobile, other countries any plausible international number, and a number typed with its own +code wins.
5. Ad attribution (f6b9434, from the other session): the ad a visitor came from travels, sealed, in the sign-up link (plan 59).

Before or with this

• The app's side of attribution is in digibranders/brandbasket-platform#86, which is still open. Releasing the website first is safe: the live app ignores the extra data. Attribution just will not be recorded on accounts until #86 is merged.
• lib/start-token.ts must stay identical in both repos.
• The landing page address changes, so update any Google Ads landing URL or GA4 filter that uses /start.
• Vercel needs PLATFORM_LEADS_URL and LEADS_API_TOKEN (the same values as the platform's) for the form to store leads and prefill the sign-up.
• Non-Indian numbers are saved with the lead but not prefilled in the app's sign-up yet (the sealed link only carries Indian numbers).

Checked

npm run lint, npm run typecheck, npm test (501), npm run build and npm run verify:html all pass. Tested on a local server: both buttons at 360px and 375px, the dropdown with mouse and keyboard, the /start redirect with its query string, the robots header, and the form request contents. Playwright e2e was not run locally; CI should cover it.
