/* ── Pattra Villa 8 · แผ่นยืนยันตัวตนลูกบ้าน (shared) ───────────────────────
   Published to https://pattra8.com/assets/resident-auth.css, loaded beside
   resident-auth.js. This is the only login surface on the site — do not fork
   it into a page's own <style>.

   Classes are `pv-auth-` prefixed so they never collide with the login-overlay
   / login-modal / login-gate rules pages carried before. Colours fall back to
   the estate palette when a page does not define the custom properties.

   Shape: a bottom sheet on phones (thumb reaches the fields and the button),
   a centred dialog from 620px up — the same breakpoint the rest of the site
   uses.
