/* Critical styling for the Wedding RSVP app.
 *
 * This file is linked from the head of Streamlit's HTML shell (see scripts/inject_head.py) so it
 * applies from the very first paint, before Streamlit's JavaScript has loaded. theme.py injects the
 * same rules again at runtime as a fallback for setups where the shell was not patched.
 *
 * Never write a less-than sign anywhere in this file, even in a comment: Streamlit's HTML
 * sanitiser drops the whole style block if its text looks like it contains a tag.
