/*
  contact.css
  BenQ Bangladesh — Contact Page
  Dedicated stylesheet for pages/contact.html: the four-card info
  strip, the two-column form + sidebar layout, form field styling
  and validation states, the location card, and the FAQ accordion.

  Depends on the design tokens in css/style.css and the .page-hero /
  .pf-btn styles from css/components.css, which this page reuses.
