/* ============================================================
   Sign In — `/sign-in` page-specific layout chrome.
   ============================================================
   Ported from `Sign In.html`'s own <style> block (couple-website-markup);
   per that design system's own convention this "flat interstitial" shell
   (.vp-*/.rp-*) is intentionally page-local rather than promoted into the
   shared styles.css (avoids a shared-bundle cache-bust for a family only
   Sign In uses so far — Reset Password/New Password/Validate Phone will
   each carry their own copy too when those land in 2.3/2.4). Everything
   below reads exclusively from the ported design tokens
   (colors_and_type.css) — no new colors/sizes invented. `.btn-pill`,
   `.intake-input`, `.field-error`, `.eyebrow`, and the shared `.np-*`
   password-field layer already live in styles.css.
