/*
  OBRAZA — styles.css
  ---------------------------------------------------------------
  HOW TO SWAP THINGS:
  • Logo: replace the hero <span class="wordmark__text" data-split> in index.html with
    <img class="wordmark__logo" src="assets/logo.svg" alt="Obraza">. .wordmark__logo is styled below.
  • Formspree ID: index.html → form action="https://formspree.io/f/FORM_ID".
  • Before/after film: index.html → <video id="film"> src + poster.

  Palette is black and white only: --paper, --ink, --rule, --muted. Nothing else.
