/* ════════════════════════════════════════════════════════════════════════
   ProveWise landing — Apple-style
   System SF stack for the Apple voice; IBM Plex Mono only for compliance
   micro-labels, tying the page to the product's own design language.
   Palette: Apple blue #0071E3 · near-black #1D1D1F · white / #F5F5F7.
   The accent was ProveWise's clinical blue #4A90E2, which sat a shade off
   Apple's own and read as "a blue product" rather than as this idiom. The
   rest of this file was already in the right voice and is left alone.

/* ── Sign in, beside every pilot CTA ───────────────────────────────────────
   The landing page sold the pilot in three places — nav, hero, closing band —
   and offered the return path only once, in the footer. A returning customer
   had to scroll the entire page to find the way back into their own records.
   Each CTA now carries a sign-in link next to it; `data-signin` makes main.js
   rewrite the href to PROVEWISE_APP_URL, exactly as it does for `data-pilot`,
   so these keep working if the marketing page moves to its own domain. */
