/*
 * Candidate comparison page styling (Issue #528).
 *
 * Phone-first: candidate cards stack in a single column on small screens and
 * flow into a responsive grid on wider ones. The side-by-side iframe
 * comparison was removed as too heavy on phones (Issue #554). Light/dark
 * themes are driven by prefers-color-scheme.
